2 Health Hazards OSHA Hazards for Construction (1926)

3 OSH Act of 1970 The purpose of the OSH Act is to assure so far as possible every working, man and woman in the nation safe and healthful working conditions and to preserve our human resources.

4 Routes of Entry Inhalation – airborne contaminants Absorption – penetration through the skin Ingestion – eating – drinking

5 OSHA Hierarchy of Control 1. Engineering controls 2. Work practice controls 3. Administrative controls 4. Personal protective equipment (PPE)

6 Types of Exposure Acute – Short term period between exposure and onset of symptoms Chronic – Long time period between exposure to an agent and the onset of symptoms

7 Exposure Limits Air Contaminants OSHA – Occupational Safety and Health Administration NIOSH – National Institute of Occupational Safety and Health ACGIH – American Conference of Governmental Industrial Hygienists

8 Exposure Limits Air Contaminants OSHA – PEL, STEL, Ceiling NIOSH – TWA, STEL, Ceiling ACGIH – TWA, STEL, Ceiling

9 Exposure Limits Air Contaminants TWA – takes into account variable exposure through a full shift, 8 hour work day STEL – limit of exposure during a short period, 15 minutes CEILING – absolute maximum level of exposure not to be exceeded

10 Exposure Limits Air Contaminants Legally enforceable – OSHA PEL – OSHA AL (action level) – OSHA EL (excursion limit)

11 Silica Special Emphasis Program (SEP) Special Emphasis Program--Silica OSHAs Industrial Hygiene initiative Collaboration of OSHA Compliance and Consultation Programs SiO 2

12 Why Target Crystalline Silica Exposure? Widespread occurrence and use Number of related deaths Number of exposed workers Health effects

13 Occurrence and Use of Silica SiO 2 - basic component of sand, quartz & granite Quartz - 2nd most common mineral in the earths crust Airborne silica is produced by:

14 – sandblasting – rock drilling – foundry work – stone cutting – drilling – quarrying – tunneling jack hammering – concrete manufacturing – demolition – asphalt pavement manufacturing Occurrence and Use of Silica

15 Construction Targeting Jack hammering Rock drilling Abrasive blasting Concrete mixing Brick and concrete block or slab cutting

16 Permissible Exposure Limit (PEL) for Silica 10 mg/m 3 % Quartz +2 = ? mg/m 3 PEL for respirable dust containing a % silica.

17 Silicosis Prevention Program Medical surveillance program – baseline examination medical and occupational history prior to exposure – every 5 years if < 20 years of exposure – every 2 years if > 20 years of exposure – baseline chest x-ray – pulmonary function tests (PFT) – x-ray upon termination of employment Source: OSHA SEP

18 Personal air monitoring program Training and information on crystalline silica Availability of air and medical surveillance data to workers Respiratory protection program Source: OSHA SEP Silicosis Prevention Program

19 Hygiene facilities and clothing change areas Recordkeeping Personal exposures below the PEL OR facility has an abatement program that provides interim worker protection Housekeeping program Regulated areas Source: OSHA SEP Silicosis Prevention Program

20 Health Effects Acute - intense crystalline silica exposure Accelerated - more intense exposure over 5 to 15 years Chronic - 20 to 45 years prolonged exposure to crystalline silica

21 Common Hazard Abrasive blasting Paint removal Renovation & demolition Road repair

22 Exposure Controls Substitution Coal slag (black beauty) Steel grit Aluminum oxide Wild stuff (frozen CO 2, walnut shells, baking soda

23 Exposure Controls Wet Methods Water suppression of dust Very effective method May be less efficient Requires supply of water and clean up Power tools with HEPA exhaust

24 Silica Case Example 39 year old sandblaster diagnosed with silicosis and tuberculosis after 22 years of abrasive blasting – shortness of breath – wheezing – chest discomfort – lung tissue samples - extensive fibrosis (silicosis)

25 Silica Case Example 49 year old man diagnosed with silicosis, emphysema, and asthma after 21 years of work as a tile installer where he was exposed to dust from cutting, drilling, and working with grout. He was a nonsmoker

26 Cadmium 29 CFR Blue-white metal Grayish-white powder Found in lead, copper, and zinc sulfide ores Compounds – highly colored from brown to yellow and red

27 Uses – electrode component in alkaline batteries – stabilizer in plastics – paints Cadmium 29 CFR

28 Short term exposure – irritation of upper respiratory tract – constriction of the throat – metallic taste – cough – flu-like symptoms Cadmium 29 CFR

29 Long term exposure – kidney damage – lung cancer – prostate cancer Cadmium 29 CFR

30 ScopeScope All occupational exposure to cadmium compounds – in all construction work construction alteration repair

31 Covered Activities Wrecking Demolition Salvage Use of cadmium containing paints Cutting, brazing, burning, grinding or welding Electrical grounding w/cadmium Installation of cadmium products Emergencies Transportation, disposal, and storage

32 DefinitionsDefinitions Action level (AL) – 2.5 g/m 3 Competent person (29 CFR ) – determines presence of cadmium – regulated areas – access – PPE – training

33 Permissible Exposure Limit PEL = 5 g/m 3

34 Exposure Monitoring Prior to performance Exposure at or above the AL – relevant plans – reports – MSDSs – other records Frequency Additional monitoring ?

35 Initial Monitoring As soon as practicable Higher concentrations – monitor while conducting task Objective data Documentation – > 5 g/m 3 – < 5 g/m 3

36 Prohibited Activities Eating Drinking Smoking Chew tobacco Apply cosmetics OR carry such products into regulated areas

37 Methods of Compliance Intermittent exposure Exposure < 30 days per year Engineering and work practice controls are not feasible – reduce exposure to lowest level – PPE

38 Methods of Compliance Employee Rotation

39 Compliance Program Exposure > PEL Written program Review and update as necessary

40 Other Requirements Hygiene areas and practices Housekeeping Medical Surveillance – 30 or more days > action level – Communicating hazards – Recordkeeping

41 Lead in Construction Standard 29 CFR SCOPE AND APPLICATION – Applies to all construction work where an employee may be occupationally exposed to lead. – Excludes construction work covered in the general industry standard.

42 Lead in Construction Standard Applies to: – Demolition – Removal and Encapsulation – New construction, alteration, repair, or renovation – Installation of products containing lead – Lead contamination/ emergency cleanup – Transportation, disposal, storage – Maintenance operations associated with construction

43 Selected Definitions LEAD – Metallic lead – All inorganic lead compounds – Organic lead soaps ~ Excludes organic lead compounds. ~

44 Selected Definitions COMPETENT PERSON ACTION LEVEL (AL) – 30 g/m 3 PERMISSIBLE EXPOSURE LIMIT (PEL) – 50 g/m 3

45 ALLOWABLE EXPOSURE (in g/m 3 ) 400 # hours worked Selected Definitions

46 INITIAL DETERMINATION – To determine whether employees are exposed at above the action level – May rely on historical data – May rely on objective data Selected Definitions

47 Exposure Assessment Lead in Construction INITIAL DETERMINATION – TASK 1 TRIGGERS: Exposure up to 500 g/m 3 (10 x the PEL) Activities include: –manual demolition of structures, hand scrapping or sanding, heat guns, power tool cleaning with dust collection systems, spray painting
