3. Hazard Assessments Assess the workplace Evaluate every job
Determine appropriate PPE
Certify the completion of the hazard assessment in writing
Slide Show Notes
The Occupational Safety and Health Administration (OSHA) requires us to assess the workplace to determine if hazards are present, or likely to be present, that necessitate the use of personal protective equipment (PPE) by workers.
Every job or task in every department in the workplace must be evaluated for hazards that may require the use of PPE.
Once hazards have been identified, we must determine appropriate PPE that will protect you from those hazards.
We must certify in writing that the PPE hazard assessment has been performed. The certification must identify the workplace evaluated, the person certifying the evaluation, and the date of the assessment.
Bring copies of your company’s completed PPE hazard assessments.

4. Head Hazard Assessment
Falling objects
Exposed electrical conductors
Low-hanging obstructions
Slide Show Notes
Let’s use this training session as an opportunity to review the potential head hazards present in our workplace.
The primary causes of head injuries are:
Falling objects
Exposed electrical conductors
Low-hanging obstructions
We will take the time to focus on each of the topics and the specific hazards associated with our workplace in the upcoming slides. Can you think of any other potential head hazards, specific to our workplace, that are not listed on the slide?
Consider inserting an additional slide that discusses other hazards specific to your workplace.

5. Falling Objects You are at risk when working below others
Incidents are difficult to anticipate
Most impact injuries occur to workers not wearing head protection
Most workers injured while doing normal jobs
Slide Show Notes
When assessing the workplace, we look for areas where employees are working below other employees or other work activities. A tool, part, bolt, piece of metal, or other object could fall and strike the head of those below.
Many of the incidents that result in head injuries are difficult to anticipate and control; that is why it is so important for us to evaluate the workplace for every potential hazard. Examples might include a bolt rattling loose from a tall machine over time and falling onto a worker below or non-routine projects such as a maintenance worker in a personnel lift working on a lighting fixture above production employees who could get hit by falling debris or objects.
The majority of impact injuries occur to workers who are not wearing head protection. These injuries could be prevented if head protection is worn.
Most head injuries occur to workers performing their normal jobs at their regular worksites. The injuries do not occur because of non-routine job functions. Instead, the injuries occur because the job or tasks are not adequately assessed for potential head hazards or the employee is not wearing the head protection the company and the job require.
Discuss areas in your workplace where employees are potentially exposed to falling objects.

6. Exposed Electrical Conductors
Electrical shock or burns could occur
Head protection insulates and protects
Select right class of head protection
Slide Show Notes
Workers who may be exposed to electrical conductors include power line workers, electricians on construction sites, and maintenance workers in general industry.
You could suffer severe electrical shock or burn if not wearing appropriate head protection when working around exposed electrical conductors.
Be especially careful if there is potential for the exposed electrical conductor to contact your head. The head protection is designed to act as an insulator to protect you from receiving a shock or burn.
Make sure the right head protection is selected for the work being done and the voltage you are exposed to.
Discuss areas in your workplace where employees might make contact with exposed electrical conductors.

7. Bump Hazards Bumps, scrapes, bruises
Low-hanging pipes, steel structures, machinery components
Nonroutine cleaning or maintenance
Slide Show Notes
Bumps, scrapes, and bruises to the head that result when a worker walks into a solid object can be serious injuries that may require stitches or staples to close the wound. These injuries can be prevented if workers wear hard hats or bump caps.
We evaluate the workplace for any low-hanging objects in your normal work or walking area that may present a bump hazard. These include pipes, steel structures, or machinery components.
We evaluate nonroutine cleaning or maintenance work that require employees to go under equipment like conveyors or other machinery. You may need to wear a bump cap or hard hat when doing these nonroutine tasks.
Discuss areas or job tasks in your workplace where employees may be exposed to potential bump hazards.

Slide Show Notes
Do you have any questions about workplace hazards to your head?

9. Hard Hat Design Resist penetration Absorb shock
High-density, light- weight polyethylene
Stamped with ANSI Z89 specifications
Slide Show Notes
Head injuries are usually caused by falling or flying objects or by bumping against a fixed object. Head protection must be able to resist penetration, which is achieved by making the helmet’s shell from a material hard enough to resist the blow.
Hard hats must also be able to absorb the shock of impact by a flying object. A shock-absorbing lining made of a headband and crown straps keeps the shell away from the wearer’s skull.
Most hard hats today are made of high-density polyethylene so they are lightweight and still meet design and testing requirements.
Helmets or hard hats used in the workplace must be designed according to the standards of the American National Standards Institute (ANSI). Helmets that meet ANSI specifications will have the manufacturer’s name, ANSI designation “Z89,” and the type and class stamped inside the shell.

10. Hard Hat Types Type I–Top impact and penetration protection
Type II–Top and side impact and penetration protection
ANSI Z89.1
Slide Show Notes
Type I hard hats and helmets are intended to reduce the force of impact resulting from a blow to the top of the head. Both cap and hat design styles can be Type I.
Type II head protection is a hat or cap that provides side impact protection as well as the top or vertical impact protection provided by the Type I hat.
The previous designations of Type I (hats) and Type II (caps) were replaced when the ANSI Z89.1 standard was revised in 1997.
Have examples of the different types of hard hats used by your company.
Show employees how to determine what type of hard hat they have.

11. Hard Hat Classes Class C – No electrical protection
Class G – Low voltage (tested at 2,200 volts)
Class E – High voltage (tested at 20,000 volts)
Slide Show Notes
Class C hard hats are not intended to provide protection against contact with electrical conductors.
Class G head protectors are intended to reduce the danger of contact exposure to low-voltage conductors. Test samples are proof tested at 2,200 volts, phase to ground.
Class E helmets and hard hats are intended to reduce the danger of contact exposure to high-voltage conductors. Test samples are proof tested at 20,000 volts (phase to ground)
The previous A, B, and C classes of electrical insulation were replaced when the ANSI Z89.1 standard was revised in 1997.
Have examples of the different classes of hard hats used by your company.
Show employees how to determine what class of hard hat they have.

12. Hard Hat Testing Temperature extremes Impact resistance
Penetration resistance
Electrical insulation
Slide Show Notes
The hard hats we provide you with have all been tested for:
Temperature extremes to ensure you are protected in all kinds of weather
Impact resistance to protect your head from excessive force
Penetration to ensure that a projectile cannot penetrate the shell of the cap
Electrical insulation to prevent electric shock

13. Standard Head Protection
Wide profile and brim
Increased ventilation
Sun protection
Suspension system
Ratchet systems
Brow pads
Slide Show Notes
Standard or classic head protection typically comes in two varieties— cap or helmet version.
Both styles have a wide profile and a brim. The cap has more of a baseball cap-style brim that extends in the front. The helmet has a brim that encircles the entire hard hat.
The wide profiles allow for increased ventilation because of the space between your head and the helmet.
The wide profiles and brims also help protect you from sun.
The typical suspension system has six points with straps that are about 1-inch wide. Some suspension systems have eight or more suspension points.
Most hard hats and helmets come equipped with some type of size adjusting ratcheting system so you can quickly adjust the helmet to the correct size.
Most hard hats and helmets also come equipped with different types of brow pads to protect your forehead and improve comfort.
Point out all of these features on the hard hats that you brought as examples to the class.

14. Highly Protective Helmet
Impact and penetration resistance from all directions
Chin strap
Air vents molded into helmet
Crown pad and brow pad
Accessories
Slide Show Notes
In addition to providing impact and penetration resistance to the top of the head, highly protective helmets will also provide impact and penetration resistance from the sides, front, and rear. This is a Type II helmet.
Highly protective helmets are also typically equipped with a chin strap that helps keep the helmet on your head during a fall. The chin straps typically have a quick-release buckle that keeps the helmet from slipping during use.
Air vent channels are often designed and then molded into the helmet to the keep you cool.
A crown pad and brow pad also help make the helmet comfortable to wear.
Accessories are often available to be attached to the hard hat, including faceshields, hearing protection, lamp brackets, etc.

15. High Temperature Hats Advanced thermoplastic materials
Utilities, welding, foundries, steel mills
Meet NFPA Standard
Exposed to 350ºF for 5 minutes
Resistant to radiant heat and flame
Slide Show Notes
High temperature hard hats and helmets are often made from technologically advanced thermoplastic materials. They are designed to meet the demands of high heat environments.
High temperature hard hats and helmets are ideal for workers in industries such as utilities, welding, foundries, and steel mills.
These hard hats and helmets are often made of the same materials as the helmets used by workers trained to fight wild forest fires. The helmets are certified to meet the National Fire Protection Association (NFPA) Wildland firefighting standard.
The NFPA standard requires that helmets can be exposed to a temperature of 350º F for 5 minutes.
Other tests include tests for standard shock and penetration resistance as well resistance to radiant heat and even flame.
Note that most plastic materials soften gradually over a wide range of temperatures. Therefore, there is no specific temperature at which they change from solid to liquid. There is no straightforward answer on the melting temperature of a given hard hat.

16. Bump Caps Protect against bumps, scrapes, cuts
Used when helmet or hard hat unnecessary
Made of lightweight hard plastic
May accommodate faceshields or visors
Do not meet ANSI Z89 standards
Slide Show Notes
A bump cap provides bump and scrape protection for a variety of industries in which workers may be exposed to low-hanging objects.
A helmet or hard hat may not be necessary because employees are not exposed to falling objects or exposed electrical conductors.
A bump cap is made of lightweight hard plastic and may have the look and feel of a baseball cap. A molded plastic inner skull cap also provides protection.
Some bump caps can also accommodate a faceshield bracket and visor.
Bump caps do not meet ANSI Z89.1 requirements. They are recommended for areas where protection is needed from head bumps and lacerations only.
Bring examples of bump caps that are used in your workplace.

17. Hard Hat Selection—Any Questions?
Any questions about choosing appropriate head protection?
Slide Show Notes
Do you have any questions about choosing appropriate head protection or the limitations of your head protection?

18. Wearing Hard Hats Backward
Type I hard hats have been tested
Crown must be symmetrical
Suspension must be reversed
Type II helmets should not be worn backward
Slide Show Notes
Many manufacturers have tested Type I hard hats according to ANSI Z standards.
The design of the crown impacts the performance of the hard hat when worn backward. Type I hard hats that have a symmetrical crown are most likely to meet the standards.
In order for the hard hat to perform and pass the ANSI test requirements, the suspension system must be reversed. The headband with the brow pad must still be against the forehead and the extended nape strap at the base of the skull. The suspension is worn in the forward, normal position and only the shell is worn backward.
Most Type II helmets cannot be worn backward because of the asymmetrical pattern used in the design to provide protection from impacts to the sides as well as the front and rear of the helmet.

19. Stickers or Markings
Adhesive stickers will not chemically damage helmets
Stickers may cover cracks or other signs of damage
Keep stickers at least 3/4 inch away from edge of helmet
Engraving is restricted to underside of brim
Do not engrave the crown area or near suspension sockets
Slide Show Notes
Many of you like to personalize your helmets or hard hats with stickers or engrave your name into the helmet material.
Adhesive stickers usually do not chemically react with helmet material, so there is little potential to affect performance under normal conditions.
However, stickers should be kept to a minimum to ensure that the hard hat may be adequately inspected for any signs of damage or aging, such as cracks.
Keep stickers at least 3/4 inch away from the edge of the helmet. This is where signs of damage typically occur first. If any surface cracks—however small—appear on the shell surface, the helmet should be removed from service and replaced immediately.
Engraving identification data on the underside of the brim of the hard hat will not adversely affect the helmet’s performance; however, engraving must be restricted to the brim.
Engraving, cutting with a knife, or drilling holes near the crown area or the suspension key sockets may result in failure of the helmet to provide protection during an impact. This could result in severe injury or even death.

20. Visibility Increase visibility to equipment operators and vehicles
High-visibility colors
Fluorescent striping
Reflective striping
Slide Show Notes
Hard hats are required to protect your head; however, they can also be used to increase visibility to traffic (road workers) or to other workers operating construction equipment, cranes, or other vehicles.
The most common high-visibility color is orange; however, there is a need to have workers stand out from safety barrels and signs that are also typically orange. Other popular high-visibility colors include green and yellow. Be careful to monitor high-visibility hard hat color during prolonged daylight exposure. Replace the helmet as soon as fading is evident to ensure continued visibility and safety.
Fluorescent striping, with stickers, can be added to normal colored hard hats to increase visibility and to make them more personalized. A stripe of orange or yellow can be wrapped around the hat.
Reflective silver striping can be added completely around the brim and on top to improve visibility even more.

21. Objects Inside a Hard Hat
Maintain clearance between shell and head
Metal part may reduce electrical insulation properties
Do not place objects above or below crown straps
Fabric winter liners or sunshades are acceptable
Slide Show Notes
The effectiveness of a hard hat may be reduced by wearing or placing objects, such as a baseball cap, underneath. Currently there are no requirements or tests to examine how objects worn inside a hard hat may affect performance. You should never carry or place anything inside a hard hat.
Clearance must be maintained between the hard hat shell and the wearer’s head for the protection system to work properly. A baseball cap or other object may limit this clearance.
A cap or other object may contain metal parts, such as a metal button, which may reduce the electrical protection provided by the hard hat.
Objects should never be placed above or below the crown straps because this will affect the performance of the hard hat.
Note that some products, such as fabric winter liners or cotton sunshades, are designed to work in conjunction with hard hats and are acceptable.

22. Useful Life of a Hard Hat
Replace every 2 years if exposed to chemicals, sunlight, temperature extremes
Date codes are molded into brims
Replace if struck by a forcible blow
Slide Show Notes
Replace hard hats after 2 years when they are worn in work environments that include sunlight, chemicals, or temperature extremes.
Most manufacturers mold date codes into the underside of the brim of a hard hat to indicate when it was made. Learn how to interpret the code, which may be in some form of code or symbol.
If the hard hat has been struck by a forcible blow of any magnitude, both the hard hat shell and the suspension system should be replaced immediately even if no damage is visible.
Discuss your company’s head protection replacement program.
Explain how to interpret the date codes of the brand of hard hat and helmets used by your company. The manufacturer can tell you how to interpret the code.

23. Maintenance and Care Clean with mild detergent and hot water
Inspect shell for damage or excess wear
Inspect suspension straps for cuts, frays, chemical damage
Never drill holes
Do not use paints or cleaning solvents
Slide Show Notes
Clean the hard hat shell and suspension system with mild detergent and hot water.
Inspect the shell for any signs of damage or excess wear, including cuts, scrapes, cracks, and holes.
Inspect suspension straps for cuts, frays, damage from chemicals, or any other signs of wear.
Never drill holes in the shell of a hard hat. This nullifies the Class E or G electrical insulation rating and may lessen the impact resistance of the helmet.
Do not use adhesives, paints, or cleaning solvents on your hard hat. They may damage the shell and lessen the effectiveness of the protection.
Show employees how to inspect the shell and the straps for any signs of damage.
If your company has a written program that describes the maintenance, care, replacement, field tests, and other requirements specific to your workplace, consider inserting an additional slide that describes your company’s specific requirements.

24. Field Test Hard Hats Compress shell sides inward 1 inch
Release pressure
Shell should return to original shape
Compare elasticity to new shell
Replace if not elastic or if it cracks
Slide Show Notes
Here is a test you can perform to determine possible degradation of the polyethylene shell of your hard hat.
Compress the shell inward from the sides about 1 inch using both hands.
Quickly release the pressure without dropping the shell.
The shell should quickly return to its original shape, exhibiting elasticity.
Compare the elasticity of your hard hat’s shell to that of a new shell.
If your hard hat does not exhibit similar elasticity to the new shell, or if it cracks due to brittleness, the hard hat should be replaced immediately.
Have everyone practice the field test with their hard hats.
