Ergonomics
Designing work to fit the capabilities of the workers.
What is the ergonomics?
Short for Personal protective equipment
What is PPE?
Prevent unexpected energization or release of hazardous energy
What is the purpose of lockout/tagout procedures?
Short for Job Hazard Analysis
What does JHA stand for?
Pull, Aim, Squeeze, and Sweep
What is the "PASS" method when using a fire extinguisher?
Musculoskeletal disorder (MSD)
What is a common ergonomic injury in manufacturing?
Safety toe boots and safety glasses
What PPE is required to walk onto the manufacturing floor?
Notify affected employees and shut down the equipment.
What is the first step in the LOTO procedure?
Conveyance and Trip hazards
What are two common physical hazards found in a manufacturing facility?
Class A ordinary combustibles, Class B flammable liquids, Class C Electrical fires
What are the three classes of fires and types of materials involved in each?
29 and 50 inches depending on the type of work
What is the ideal height range for workstations?
To ensure there are no defects or damage that could reduce protection.
Why is it important to inspect PPE before use?
To ensure only the person who applied the lock can remove it
Why is it important to use a personal lock during LOTO?
Engineering control changes the physical environment, Administrative control changes work practices.
What is the difference between an engineering control and an administrative control for hazard mitigation?
Check the pressure gauge, ensure pin is intact, and confirm no physical damage.
How do you properly inspect a fire extinguisher to ensure it is ready to use?
A tool used to assess the risk of lifting tasks.
What is the NIOSH lifting equation?
Reduces grip strength and leads to ergonomic strain.
What could happen from the use of incorrect gloves?
Serious injury or death
What is one risk associated with failing to follow LOTO procedures properly?
It's severity and likelihood of occurence.
How do you assess whether a hazard is critical in a JHA?
To prevent ignition or fuel sources from coming into contact with electrical sparks.
Why is it important to keep combustible materials away from electrical equipment?
Coupling, Trunk Asymmetry, frequency, duration, horizontal hand distance, and vertical distance.
What factors contribute to the recommended weight limit determined by the NIOSH lifting equation?
The chemical's physical state, duration of exposure, and required protection level.
What are the key factors when selecting appropriate PPE for chemical hazards?
Use group lock boxes and ensure everyone removes their personal lock only after confirming it's safe.
How do you ensure all members are safe in a team-based LOTO?
Elimination, Substitution, Engineering controls, Administrative controls, and PPE
What are the levels of the hierarchy of controls
A Fixed fire suppression system is automated, like sprinklers, while a portable extinguisher is manually operated.
What is the difference between a fixed fire suppression system and a portable extinguisher?
