14. Hazards associated with saw cutting areas include (select all that apply):
    1. Drops – Correct, drops are short pieces of stock left after bar stock has been used and can cause a trip hazard.
    2. Extreme light – Extreme light hazards are related to welding and arc or torch cutting and not sawing equipment.
    3. Tripping – Correct, due to stock lengths being long, they typically encroach on walkways.
    4. Sharp edges – Correct, saws create sharp edges which can cause cuts.
15. True or false: Chips is the term used to describe the small, sharp, and often hot byproduct created during a machining operation.

Answer Key

1. False – Correct, the OSH Act requires employers to protect employees from KNOWN hazards, not ALL hazards.
2. Machine Guards – Correct. Machine guardian is an OSHA standard; Hearing Protection – Correct. Hearing protection is an OSHA standard; Respiratory protection – Correct. Respiratory protection is an OSHA standard
3. SDS/Safety Data Sheet – You can obtain a Safety Data Sheet (SDS) from the chemical manufacturer.
4. False – Correct, there are 16 component sections of SDS.
5. Waste Minimization – Correct. Evaporating off the water content will reduce the amount of HAZWASTE disposed of.
6. Correct: small – Small” fires such as waste basket size should be engaged with a hand held fire extinguisher.
7. False – Correct, Elimination, Substitution, Engineering Controls and Administrative controls should be evaluated before deciding on PPE as the solution.
8. Cotton – Correct, cotton provides better protection from hot material
9. True – Correct, if PPE is not comfortable, we tend to not use it.
10. Correct: written – A well defined written program must be established when respirators are required in a work environment.
11. Protect against non-toxic dust – Correct, a dust mask can be worn to protect against non-toxic nuisance dust
12. False – When worn correctly, a N95 respirator can remove 95% of airborne particles. However, it is not rated for chemical protection
13. Correct: falling – Correct, falling objects can cause serious injury.
14. Drops – Correct, drops are short pieces of stock left after bar stock has been used and can cause a trip hazard; Tripping – Correct, due to stock lengths being long, they typically encroach on walkways; Sharp edges – Correct, saws create sharp edges which can cause cuts.
15. True – Yes, the general term used to describe the byproduct of machining processes is chips.
