2 Introduction - Basic Safety Standards:AC-IFOS-2. Understand and practice construction safety.2.1- Demonstrate knowledge of use and care of PPE.2.2 - Demonstrate a basic knowledge of OSHA and its regulations.2.3 - Demonstrate a basic knowledge of safety as related as relates to personal safety,ELACC9-10SL2: Integrate multiple sources of information presented in diverse media or formats (e.g., visually, quantitatively, orally) evaluating the credibility and accuracy of each source.ELACC9-10SL4: Present information, findings, and supporting evidence clearly, concisely, and logically such that listeners can follow the line of reasoning and the organization, development, substance, and style are appropriate to purpose, audience, and task.
3 IntroductionThroughout the day, many tasks will be repeated with little conscious thought.This can make work dull and increases the chance of an accident.Safety consciousness is a vital part of your work.Safety training is conducted to make you aware that dangers exist all around you every day.Jobsites are always changing and new hazards are continuously emerging.
5 Importance of SafetySafety is a learned behavior and attitude, as well as a way of working.A safety culture is created when the whole company sees the value of a safe work environment.
6 Importance of SafetyCompanies with a strong safety culture have lower accident rates and a lower turnover of personnel.Other benefits…fewer at-risk behaviorslower absenteeismhigher productivitycan lower a company’s Experience Modification Rate (EMR)
7 Importance of Safety Factors... perceiving safety as a core value. strong leadership.the involvement of all employees.using the workplace as learning environment.continually monitoring performance.effective communication of safety goals.
8 AccidentsAn accident is defined as an unplanned event that may or may not result in personal injury or property damage.Accidents can happen to anyone at any time, in any place.
9 Accidents 5 Types of Accidents: Near-miss: no one injured and no property damageProperty damage: results in damage to tools, material or equipment.Minor injuries: minor cuts, bruises, or strains but worker returned to full duty the next day.Serious injury: results in temporary or permanent disability.Fatalities: death
10 Accident CostsWhen an accident occurs, there are direct costs such as the medical costs of the injured worker, and indirect costs such as lost productivity and the cost of training a replacement worker.Direct Cost: Can be foreseenMedical BillsWorker’s CompensationLiability Insurance PremiumsIndirect, Hidden cost: Are not foreseenProperty damageEquipment damageProduction delaysSupervisory timeRetrainingImage/Morale
11 Indirect CostIndirect or hidden costs can exceed direct costs by two to seven times.
12 Activity: 5 Types of Accidents Objective: List the 5 types of accidents and give examples of each.Group Task: Prepare a Tree Map to classify each type of accident and give examples of each. Be prepared to present work to the class (p 1.2).
14 Review What is safety consciousness? Is safety a learned behavior? ExplainWhat is a safety culture and what are the benefits?What is the definition of an accident?What are 5 types of accidents?What is the difference between Direct Cost and Indirect Costs?How much do hidden costs exceed the amount of direct costs?
15 Day 2QOD: How much do hidden costs of accidents usually exceed the direct cost?Two to seven timesAgenda:1. QOD & Measurements2. Basic Safety PP3. Video – Failure to Communicate4. Activity – 9 Causes of Accidents5. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
16 What Causes Accidents? 9 Causes of Accidents failure to communicate rationalizing riskunsafe conditionspoor work habitsalcohol and drug abuselack of skillintentional actsunsafe actsmanagement system failure
17 What Causes Accidents?Poor Work Habits such as goofing off, carelessness, and horseplay can result in serious accidents.
18 What Causes Accidents?Rationalizing Risk is the act of ignoring safety warnings and practices because you make an excuse for doing so.Examples…Crossing boundaries because no activity is in sight.Not wearing safety goggles because it will only take a minute to make a cut.Removing your hard hat because you are hot and you can not see anyone working overhead.Not tying off your fall protection because you only have to lean over about a foot.
19 What Causes Accidents?Unsafe Condition is the physical state that is different from the acceptable, normal, or correct condition found on the job site.Examples…Congested workplacePoor lightingExcessive noise
20 What Causes Accidents?Alcohol and Drug Use are a major contributor to accidents on and off the job.Many states prevent workers from collecting insurance benefits if they are injured while under the influence of alcohol or illegal drugs.You should also be aware that some prescription drugs can affect performance as well. If you are taking prescription drugs, be sure you know how they can affect you.
21 What Causes Accidents?An Intentional Act is an attempt by someone such as a disgruntled or angry worker to deliberately cause an accident.
22 What Causes Accidents?An Unsafe Act is conduct that can lead to an accident. Unsafe methods are often easier or more convenient than doing something right.This makes it easier to rationalize doing something that is unsafe.
23 What Causes Accidents?Management System is when your employer and the construction site management must have a system in place to:prevent accidentsidentify conditions that can cause accidentstrain employees in accident prevention.The absence of such a program is a management system failure
24 Housekeeping The major goal of housekeeping is to prevent accidents. Housekeeping is the process of keeping the job site and your immediate work area neat and clean, will help a lot in preventing accidents.The work area should be well lighted and have good ventilation.Tools, equipment, and materials should not be left lying around for people to trip over.The major goal of housekeeping is to prevent accidents.
26 What Causes Accidents?Failure to Communicate means that workers and supervisors should never assume that others know what to do.Safety information is most often communicated with signs.All work sites have specific markings and signs to identify hazards and provide emergency information4 types of signs:InformationalSafetyCautionDanger
28 Informational Signs color – blue provide general information. Examples:No AdmittanceNo TrespassingFor Employees Only
29 Safety Signs color – green panel with white letters give general instructions and suggestions about safety measures.Examples:First-aid stationEmergency eye wash stationEvacuation routesMaterial Data Safety Sheets (MSDS)Exits
30 Caution Signs color – black panel with yellow letters tell you about potential hazards or warn against unsafe acts.Examples:Hearing and eye protection requiredRespirators are requiredSmoking is not allowed
31 Danger Signs color – red, black, and white tell you that an immediate danger exist and that you must take precautions to avoid an accident.Examples:Defective equipmentFlammable liquidsSafety barrierHigh voltageEmergency stop button
32 Activity 9 Causes of Accidents Objective: To choose a cause of accidents and illustrate examples of the chosen cause.Group Task: Prepare a Multi-Flow Map with 3 causes and 3 effects from one of the 9 causes of accidents (pp ).
34 Review What are some of the Causes of Accidents? What is Rationalizing Risk?Poor Housekeeping, excessive noise, and inadequate guards for moving part are considered which cause of accident?What is the major goal of housekeeping?What are the 4 Types of SignsWhat is a Management System Failure?
35 failure to communicate, rationalizing risk, unsafe conditions Day 3QOD: List three of the nine causes of accidents on the jobsite?failure to communicate, rationalizing risk, unsafe conditionsAgenda:1. QOD and Measurements2. Basic Safety PP3. Video – OSHA Introduction4. Activity – OSHA Inspections5. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
36 OSHA Regulations Occupational Safety and Health Act of 1970. Mission: to save livesprevent injuriesprotect the health of American WorkersCode of Federal Regulation (CFR)29 CFR Part 1910 – covers OSHA’s standards for the general industry.29 CFR Part covers OSHA’s standards for the construction industry.
38 OSHA RegulationsThe General Duty Clause - invoked when a standard does not address a hazard.If the following elements are present , a general duty clause citation may be issued:The employer failed to keep the work place free of hazard.The hazard was recognized, but not corrected.The hazard was causing, or likely to cause, death or serious physical harm.There was a feasible and useful method to correct the hazard.
39 OSHA Regulations Employee Rights and Responsibilities If a worker has been discriminated against for asserting his or her OSHA rights, that person has 30 days from the time of the incident to file a complaint with OSHA.Your employer is required by OSHA to maintain your job-related medical records for 30 years after you leave employment.
40 OSHA RegulationsInspections are conducted to insure employers are compliant with standards. There are 6 types.Immanent danger: conducted when workers face an immediate risk of death or physical harm.Catastrophic: performed after an accident that requires hospitalization of 3+ people. Employers are required to report fatalities and catastrophes to OSHA within 8 hours.Worker complaint: conducted due to complaint by worker.Programmed: aimed at high-risk areas.Follow-up: completed after citation to assure employer has corrected citation.Monitoring: used for long-term abatement follow-up and to assure compliance with variances.
41 OSHA RegulationsA competent person is someone who is capable of identifying existing and predictable hazards and has authorization to take prompt corrective measures to eliminate such hazards.To help employers provide a safe workplace, OSHA requires companies to provide a competent person to ensure safety of their employees.
42 OSHA RegulationsThere are three categories of on-the-job events: injuries, accidents, and incidents.An incident is anything that could have caused and injury or damage but, because it was caught in time, did not.An accident is anything that causes an injury or property damage.An injury is anything that requires treatment, even minor first-aid.
43 Job Safety AnalysisJob Safety Analysis (JSA) is one approach to hazard evaluationIn a JSA, the task at hand is broken down into its individual parts or steps and then each step is analyzed for its potential hazards.For example in a Fall Protection Work PlanRecognize HazardsProvide SolutionsIdentify ProceduresDefine Training
45 Hazard EvaluationRisk assessment is a measure of the probability, consequence and exposure related to an event.Components:Probability is the chance that a given event will occur.Consequences are the results of an action, condition or event.Exposure is the amount of time to which someone or something is exposed.
46 Activity: OSHA Inspections Objective: List important facts about 5 of the 6 types of OSHA inspection.Group Task: Prepare a Tree Map to list important facts about 5 of the 6 types of OSHA inspection. Be prepared to present work to the class. (pp. 1.11)
48 Review What does OSHA stand for, what is their mission? What is the General Duty Clause?How long does OSHA require your employer to keep your medical records?How many days does a worker who has been discriminated against under OSHA rights have the right to file a complaint?What is the process of preparing a Job Safety Analysis?What are the components in risk assessment?
49 Day 4 QOD: What is OSHA’s mission? to save lives, prevent injuries, protect the health of American WorkersAgenda:1. QOD2. Safety Pledge3. SLO Test4. Activity – OSHA Inspection5. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
50 Day 5 QOD: In your own words, describe OSHA. …. Agenda: 1. QOD and Measurements2. Safety Pledge3. Basic Safety PP4. Video – 4 High-Hazard Areas5. Activity – Fall Protection and Job Hazard Analysis6. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
52 OSHA Regulations The 4 high-hazard area Falls from elevation are accidents involving failure to properly use appropriate fall protection.Struck-by accidents involve unsafe operation equipment, machinery, vehicles i.e. unsafe rigging operations.Caught-in accidents involve unsafe operation equipment, machinery, vehicles i.e. improper procedures at a trench site.Electrical shock accidents involve contact with overhead wires, use of defective tools, or improper ground fault protection.
54 Personal Fall Arrest Systems (PFAS) A PFAS consists of a body harness, lanyards, lifeline, connecting devices, and anchor points.Always have your personal fall arrest system, PFAS, inspected monthly by a competent person.
55 Personal Fall Arrest Systems (PFAS) The lanyard attaches to the D-ring. The D-ring or support point on a safety harness should be placed to the rear, between your shoulder blades.A dual lanyard is an excellent method to enhance safe work operation.
59 Fall ProtectionAny opening in a wall or floor is a safety hazard. These openings can be guarded or they can be covered.Railings are used across wall openings or as a barrier around floor openings to prevent falls.Warning barricades alert workers to hazards but provide no real protection.Warning barricade tape colored red means danger and no one can enter.Yellow signifies caution and allows entry. A yellow and purple sign is used to indicate a radiation hazard.Protective barricades give both a visual warning and protection from injury. No one should be able to get past a protective barricade.
62 Activity: 4 High Hazard Areas Objective: List the 4 High-Hazard Areas and give 3 examples of each.Group Task: List the 4 High Hazard Areas on a Tree Map and give three examples of each. Review each example and be prepared to discuss with the class, a minimum of 3 each is required per area (p.1.13).
64 ReviewWhat part of a safety harness does the lanyard attach to for safety?Where should the D-ring on a safety harness be placed?Who should inspect your fall arrest system monthly?What is the process of preparing a Job Site Analysis?Which type of OSHA inspection involves reporting fatalities and catastrophes to OSHA within 8 hours?
65 To the rear, between your shoulder blades. Day 5QOD: Where should the D-ring on a safety harness be placed?To the rear, between your shoulder blades.Agenda:1. QOD and Measurements2. Safety Pledges3. SkillsUSA – September 12th4. Basic Safety PP5. Video –Ladder Safety6. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
67 Ladders Ladders are used to perform work in elevated locations. Metal ladders conduct electricity and must not be used around electrical equipment or wiring.Types:Straight laddersExtension ladderStepladder
68 LaddersLadders should be secured at the bottom and top to prevent accidental movement.
69 Ladders Ladders are used to perform work in elevated locations. Metal ladders conduct electricity and must not be used around electrical equipment or wiring.Do not carry tools while climbing a ladder; use a hand line or tag line.Types:Straight laddersExtension ladderStepladder
71 Ladders - StraightStraight ladders consist of two rails, rungs between the rails, and safety feet on the bottom of the rails.Using straight laddersIf you are going step off a ladder onto a platform or roof, the top of the ladder should extend at least 3’ feet above the point where the ladder touches the platform, roof, side rails, etc.
72 Ladders - ExtensionExtension ladders are actually two straight ladders. They are adjusted so you can adjust the overlap between them and change the length of the ladder as needed.Using an extension ladder4 :1 Ratio – The base needs to be set-back 1’ for each 4’ of length to the upper support point.3 Point Contact - Either have both hands and one foot or two feet and one hand touching the ladder at all times.The highest safe standing level on an extension ladder is the 4th rung from the top. Never climb over the 4th rung from top.Check to make sure the section locking mechanism, rung lock, is fully hooked over the desired rung.
77 Ladders - StepStep ladders are self-supporting ladders made of two sections hinged at the top.Using an step ladderWhen positioning a step ladder, be sure that all four feet are on a hard, even surface.
79 StairwaysStairways are also routinely used on construction sites where there is a break in elevation of 19” or more, and no ramp, runway, sloped embankment, or personal hoist is provided.OSHA requires that at least five foot-candles of light be available in stairways.An example of an unsafe condition on a jobsite is inadequate lighting in a stairway.
80 Review How far should a ladder extend past a platform? What is the highest safe standing level on an extension ladder?What should be used to transport tools from one floor to another?What is the 4:1 ratio referring to in ladder safety?What is 3 point contact referring to in ladder safety?What is an example of an unsafe condition?
81 Day 6 QOD: What is the 4:1 ratio? A ladder safety rule where the base of a ladder must extend out 1’ horizontally for every 4’ of vertical distanceAgenda:1. QOD and Measurements2. Safety Pledges3. Basic Safety PP4. Video – Scaffolds5. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
83 ScaffoldsScaffolds provide a safe elevated work platform for people and materialsTwo basic types of scaffolds are commonly used in construction:Manufactured scaffoldsRolling scaffoldsScaffolds are made ofpainted steelstainless steelaluminum.
84 ScaffoldsOSHA regulations provide for a system of tags to show the status of scaffolding.A green tag means the scaffold is okay for use.A yellow tag means the scaffold can only be used with a safety harness and lanyard because it lacks some safety feature.A red-tagged scaffold may not be used because it is being assembled or taken down.If a scaffold is more than 10’ high, it must have top rails, mid-rails, and toe-boards, and all connections must be pinned.Cross-bracing is also required, and the work area must be completely planked.A competent person must inspect a scaffold before it can be used.
88 Struck-by Hazards Account for 18% of construction fatalities. Primary Causes:Vehicle and Equipment StrikesFalling ObjectsFlying Objects
89 Vehicle and Equipment Strikes Most common cause of accidents involving highway workers.When working on the ground near moving vehicles:Never get into the operator's blind spot.Keep off equipment unless authorized.Wear reflective or high visibility vestWhen operating equipment on the job site:Always wear a seatbeltLook to the rear and sound the horn before backing up. If your rear vision is blocked get a signaler to direct you.Turn off the engine and set the breaks before you leave the vehicle.
90 High Visibility VestWearing a reflective or high visibility vest is the best way to protect yourself when working near moving vehicles and equipment.
91 Falling ObjectsWorkers on construction sites are at risk from falling objects. Avoid standing beneath any load on a crane or lift, and wear a hard hat at all times.Use toe-boards, debris nets, catch platforms, or canopies to catch or deflect falling objects.To prevent stacked material from falling over, never stack material higher than a 4:1 height-to-base ratio.
93 Flying ObjectsPower tools and activities such as pushing, pulling or prying can cause objects to become airborne.Chipping, grinding, brushing or hammering can cause objects to become airborne.To protect against flying objects…Use eye protection i.e. safety goggles, face shields.Inspect tools to make sure protective guards are in good condition.
95 ReviewAt what height must you don a harness when working on a scaffold with no rails?What are the tag colors associated with scaffolding and what do they mean?What can you use on a scaffold to prevent falling objects?What is used to protect workers from moving parts?How many foot-candles of light does OSHA require on stairways?What are three rules that must be followed when operating equipment on a job site?
96 Day 7 QOD: How far past a platform should you extend a ladder? 3’ Agenda:1. QOD & Measurements2. Safety Pledges3. SkillsUSA – September 18th4. Activity – Evacuation Procedures5. Activity – Donning a Safety Harness6. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
97 Activity: Donning a Safety Harness Objective: To demonstrate proper use of a safety harness.Individually, practice donning the safety harness.Next, determine who the best in your group is at donning a safety harness.Next, fill in bracket and determine winner.
98 Activity: Evacuation Procedures Objective: To demonstrate the route for each student to take during an emergency - including Fire, Tornado and Bomb Threat.1. As a class, exit the building at the rear entrance as if there were a Fire.2. Next, exit the building at the rear entrance as if there were a Bomb Threat.3. Next, review the procedure for a Tornado Drill.4. On a sheet of paper write the procedures down for a Fire and a Bomb Threat. Be sure to include the final destination.5. Label the sheet on the top as Activity #3 and insert it into your notebook.
99 Day 8QOD: When working on scaffolding, what is a good way to protect against falling objects?Use protective measures such as toe boards, debris nets, catch platforms, or canopies to catch or deflect falling objects.Agenda:1. QOD and Measurements2. Safety Pledges3. Basic Safety PP4. Video – Trench5. Activity – Benching and Sloping6. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
101 Caught-In-Between Hazards Congested work sites, heavy equipment, and multiple trades can contribute to caught-in-between hazards.Construction workers often have to work in trenches or excavations, where cave-ins and falling objects are common hazards.Primary Causes:Trench/Excavation CollapseRotating EquipmentUnguarded Parts
102 Caught-In-Between Hazards Excavation vs. TrenchAn excavation is any man-made cut, cavity, trench, or depression formed by the removal of earth or soil.A trench is an excavation that is deeper than it is wide, and usually not wider than 15'.Hazards include…Cave-InsWater AccumulationFalling ObjectsCollapse of Nearby Structure
104 Caught-In-Between Hazards Soil Type is a key factor in determining the type of Protective System necessary to ensure that the trench will be safe.To be safe, treat soil as if it is type C soil unless proven otherwise.Trenches and excavations must be inspected at least daily by a competent person.
105 Caught-In-Between Hazards 4 Types of Soil TypesSolid RockExcavation walls stay vertical as long as the excavation is open.Type A SoilFine grained and cohesive. Particles to small to see with the eye. Clay and CalicheType B SoilAngular rock, silt, and similar soil.Type C SoilCourse grained, granular. Particles are visible to the naked eye. Sand, Gravel
106 Caught-In-Between Hazards Protective systems protect workers from cave-ins, materials that can fall or roll into an excavation, and collapse of adjacent structures.Sloping and benching are similar forms of trench protection that cut away and slant the excavation face.Benching systems cannot be used in type C soils, because they will not hold the bench properly and will collapse.
107 Caught-In-Between Hazards Sloping - a method in which the sides of an excavation are cut back to a safe angle using relatively smooth inclines
108 Caught-In-Between Hazards Benching – similar to sloping, but instead of smooth inclines, the sides of the trench wall are cut back using a series of steps.
109 Caught-In-Between Hazards Both systems call for a safe angle called the maximum allowable slope (MAS).Type A soil allows the steepest slope, while type C soil allows the shallowest slope.Type A Soil: 3/4 – 1, or 53 degreesType B Soil: 1 to 1, or 45 degreesType C Soil: 11/2 to 1, or 34 degreesType AType BType C
111 Activity: Types of Soil and Protective Systems Objective: Compare and contrast benching and sloping techniques.Group Task: Prepare a Double Bubble Map to compare and contrast benching and sloping and determine which soils are appropriate in each system. (pp )
113 Review What is an Excavation? What is a Trench? What are the 4 types of soil?What are different types of protective systems?Which soils can be used on the sloping system?Which soils cannot be used with a benching system?
114 Day 9 QOD: What is an excavation? Excavation is any man made cut, cavity, trench, formed by the removal of soil.Agenda:1. QOD and Measurements2. Safety Pledges3. SkillsUSA Membership– Tomorrow4. SkillsUSA Champion’s Rally – Tomorrow5. Basic Safety PP6. Video – Lockout/Tag-out7. Activity – Shoring and Shielding8. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
115 Caught-In-Between Hazards Many trenches are in narrow places, so sloping and benching are not options.In these situations, support systems like shoring or shielding must be utilized.Shoring vs. ShieldingShoring consist of plating held firmly in place with expandable braces.Shielding structures, or trench boxes, are placed inside trenches or excavations, and are strong enough to protect workers in the event of a cave-in.
116 Caught-In-Between Hazards Shoring structure vs. Shielding StructureSoil, materials and equipment should be placed at least 2’ from the edge of the excavation.
117 Caught-In-Between Hazards Keep all materials and heavy equipment at least 2' from the edge of the excavation.Barricades may be required to contain falling material.Workers must be able to safely enter and exit a trench using a stairway, ladder, or ramp. There must be an exit every 25' for every trench over 4' deep.
122 Electrical Safety Guidelines The three-wire system is one of the most common safety grounding systems used to protect you from accidental electric shock.The third wire is connected to a ground.With every power tool, use an assured ground program or GFCI.Double insulated cords are also effective in preventing shocks when using power tools.Use some sort of a Ground Fault Circuit with every tool. They are designed to shut off electrical power within 1/40 of a second.
126 Activity: Types of Soil and Protective Systems Objective: Compare and contrast shoring and shielding techniques.Group Task: Prepare a Double Bubble Map to compare and contrast shoring and shielding and determine which soils are appropriate in each system. (pp )

What are the 4 types of soil?What are different types of protective systems?Which soils can be used on the sloping system?Which soils cannot be used with a benching system?What are some ways to prevent electrical shock?What is a lock/out tagout system?
129 Day 10 QOD: What can protect you from electric shock? Three-wire cord, double-insulated cord and ground fault circuit interrupters.Agenda:1. QOD & Measurement2. Safety Pledges3. Basic Safety PP4. Video – Exposures5. Activity – Personal Protection Equipment6. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
130 Personal Protective Equipment (PPE) You will be responsible for wearing appropriate PPE on the job and in the lab.PPE includes…Hard HatEye and Face ProtectionGlovesFoot ProtectionHearing ProtectionRespiratory Protection
131 Personal Protective Equipment (PPE) Eye and Face Protection
132 Personal Protective Equipment (PPE) Gloves, Inspecting1. Stretch the glove.2. Trap air inside the glove.3. Try to detect any air escaping.4. If inspection fails, dispose of it.
133 Personal Protective Equipment (PPE) Hearing ProtectionClean earplugs with soap and water to prevent ear infections.
134 Personal Protective Equipment (PPE) Respiratory SystemA full face-piece mask with chemical canisters is used to protect against brief exposure to dangerous gases and fumes.Wherever there is danger of an inhalation hazard, you must use a respirator.
135 Personal Protective Equipment (PPE) Respiratory System
137 Material Safety Data Sheet (MSDS) MSDS must accompany every shipment of a hazardous substance and must be available to you on the job site.The following is found on an MSDS:Emergency first-aid proceduresManufacturer contact informationIdentity of the substanceSpecial control measures
138 ExposureDefinition: refers to contact with a chemical, biological, or physical hazard.Types of exposure hazards:Lead – toxic metalAsbestos – prolonged exposure can cause lung cancer, asbestosis, and a cancer called mesothelioma.Silica – causes silicosis and lung cancerBloodborne Pathogens – transmitted by contact with an infectious person’s bloodChemical Splashes – in the event that this happens use shower or eyewash station
140 Activity: Types & Uses of PPE Objective: Name and determine the appropriate use for each type of PPE.Group Task: Prepare a Tree Map to classify each type of PPE i.e. safety glasses, safety harness, gloves, etc. Be prepared to present work to the class.
142 Review What are the appropriate steps to don electrical gloves? What must be included with every shipment of a hazardous substance and made available to workers on the jobsite?What kind of information is found on in MSDS?What is Asbestos and what harm can it cause to a worker?
143 Material Safety Data Sheets, MSDS Day 11QOD: What must be included with every shipment of a hazardous substance and made available to workers on the jobsite?Material Safety Data Sheets, MSDSAgenda:1. QOD & Measurement2. Safety Pledges3. Basic Safety PP4. Video – Heat Stress5. Activity – Heat Stress6. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
144 Proximity WorkProximity work refers to work done near, but not in direct contact with a hazard such as hot piping, energized electrical equipment, operating machinery, pressurized or high temperature systemsBarricades may be needed to avoid contact with these hazards, and special precautions may be needed during rigging operations to prevent objects from falling on the hazard.
146 Welding and Cutting Hazards Welding can create an intense arc capable of damaging the eyes of anyone looking directly at it.Proper eye protection, including flash goggles, must be worn by everyone in the vicinity of arc welding.When gas welding, welders are required to wear tinted goggles with a filter lens of not less than No. 4UV radiation from a welding arc can cause flash burns to the eyes and skin.Welding shields may be needed to protect workers near the welding activity.
147 Welding and Cutting Hazards Different hoses are used for different gases.The fuel gas hose is usually red, but may be black. Its coupling nut has a left-hand thread, which is the opposite of the usual thread pattern.The oxygen hose is green and has a right-hand thread nut for connecting the torch.Look for charred on hoses. Charred sections of a welding hose may have been caused by flashback, result of welding flame flaring up.
150 Heat StressHeat stress occurs when abnormally hot air or high humidity prevent your body from cooling itself fast enough.Results of heat stress:Heat cramps – muscular pains and spasms caused by heavy exertion.Heat exhaustion – occurs when people exercise heavily or work in a warm, humid place where body fluids are lost through heavy sweating.Heat stroke – is life threatening and occurs when the body-temperature control system, which produces sweat to cool the body, stops working.
151 Cold StressCold Stress occurs when your body temperature drops just a few degrees below normal, which is about 98.6°F.Results of Cold StressFrostbite – a dangerous condition that can have lifelong effects on your body by loosing fingers, hands, limbs, etc.Hypothermia – a serious, potentially fatal condition and you do not have to be below freezing to be at risk.
153 Activity: Types of Cold and Heat Stress Objective: List facts about each type of Cold and Heat Stress covered today.Group Task: Prepare a Tree Map to classify each type of Cold and Heat Stress. Be prepared to present work to the class (pp ).
155 ReviewWhat type of work refers to work done near, but not in direct contact with a hazard?When gas welding, what is the minimum filter lens a welder is required to wear for eye protection?What are the effects of Heat Stress?What are the affects of Cold Stress?When welding, what can cause charred sections of a welding hose close to the torch?What color is the fuel gas hose?What color is the oxygen hose?
156 Heat cramps, exhaustion, stroke Day 12QOD: What are the three results of heat stress?Heat cramps, exhaustion, strokeAgenda:1. QOD & Measurement2. Safety Pledges3. Basic Safety PP4. Video – Confined Space5. ReviewStandards:AC-IFOS-2. Understand and practice construction safety.
158 Confined SpaceA confined space is one that is large enough to work in, but has limited means of entry and exit, as well as limited ventilation.
159 Permit-required confined space A permit-required confined space is one that has been evaluated by a qualified person and found to have actual or potential hazards, therefore, a written permit is required to enter such spaces.Confined spaces may contain hazardous fumes. Or, the work being done, such as welding or metal cutting, may introduce hazardous fumes.
162 Construction Ergonomics Ergonomics is the study of the physical impact that work-related movements, motions, and postures have on workers.Repetitive motion and constant vibration can cause injuries.Lifting is a six-step process that uses the muscles of the legs to avoid back injury.
164 Fire Hazards Fire is a potential hazard on any construction site. A fire needs fuel, heat, and oxygen to start. Fuel is any material that will burn, and oxygen is always available in the surrounding air.Heat is any action that will raise the fuel's temperature to the flash point, which starts the fire.
