COMPLETE 56 QUESTIONS
Question 1: Under OSHA's Laboratory Standard, what written program is required
when hazardous chemicals are used in a covered laboratory?
Choices:
1) Exposure Control Plan 2) Chemical Hygiene Plan 3) Hazardous Materials Manifest 4) Emergency Action Permit
Correct Answer: Chemical Hygiene Plan
Explanation: OSHA 29 CFR 1910.1450 requires a written Chemical Hygiene Plan for covered laboratory use of hazardous chemicals. The plan describes procedures, equipment, PPE, and work practices used to protect employees and keep exposures within applicable limits.Page 1
Question 2: How often must an employer review and evaluate the e�ectiveness of its Chemical Hygiene Plan under OSHA's Laboratory Standard?
Choices:
1) At least annually 2) Every three years 3) Only after an OSHA inspection 4) Only when a new chemical is purchased
Correct Answer: At least annually
Explanation: The OSHA Laboratory Standard requires the Chemical Hygiene Plan to be reviewed and evaluated at least annually and updated as necessary. Changes in hazards, procedures, equipment, or personnel can also justify earlier updates.Question 3: A researcher is assigned a procedure that introduces a new hazardous chemical exposure not covered in prior training. When should additional hazard information and training be provided?
Choices:
1) At the next annual safety meeting 2) After the �rst successful experiment 3) Before the new exposure assignment begins 4) Only if air monitoring exceeds a limit
Correct Answer: Before the new exposure assignment begins
Explanation: OSHA requires information and training at initial assignment to work with hazardous chemicals and before assignments involving new exposure situations. Training should therefore occur before the researcher starts the new procedure.Page 2
Question 4: Which action best re�ects safe pre-work planning for a new laboratory chemical procedure?
Choices:
1) Begin with a small amount and look up hazards only if a problem occurs 2) Review the SDS, applicable SOP, controls, and emergency procedures before starting 3) Rely on the container color to judge the chemical's hazard 4) Use gloves as the only control because PPE is the last barrier Correct Answer: Review the SDS, applicable SOP, controls, and emergency procedures before starting Explanation: Safe laboratory work begins with hazard review and planning. The SDS, standard operating procedure, required engineering controls, PPE, and emergency response steps should be understood before the chemical is handled.
Question 5: Which practice is most appropriate in an area where hazardous
laboratory chemicals are used or stored?
Choices:
1) Eating is allowed if food stays on a separate bench 2) Drinks are allowed if they have screw caps 3) Food may be stored in the laboratory refrigerator if it is sealed 4) Eating and drinking should be prohibited in the laboratory work area Correct Answer: Eating and drinking should be prohibited in the laboratory work area Explanation: Food and drink can create an ingestion pathway for hazardous chemicals. OSHA laboratory guidance recommends prohibiting eating, drinking, gum chewing, applying cosmetics, and similar activities in areas where hazardous chemicals are used or stored.Page 3
