NIOSH School Chemistry Guide Flashcards
What is the purpose of the School Chemistry Laboratory Safety Guide?
To provide teachers with information on chemical management and safe laboratory practices.
Which federal agency partnered with ACS to publish the guide?
The U.S. Consumer Product Safety Commission (CPSC).
What is the primary responsibility of teachers in a chemistry lab?
To ensure a safe learning environment by following safety practices and supervising students.
Name one key administrative control recommended in the guide.
Developing a Chemical Hygiene Plan (CHP).
What document must be available for every hazardous chemical in the lab?
Safety Data Sheet (SDS).
How should incompatible chemicals be stored?
In separate, designated storage areas to prevent dangerous reactions.
Why should mercury-containing equipment be removed from labs?
To prevent toxic mercury exposure from spills or breakage.
What type of ventilation is necessary in chemical storage rooms?
Mechanical exhaust ventilation to the outside.
What are PPE items students must wear during experiments?
Safety goggles, gloves, and lab aprons or coats.
How should flammable chemicals be stored?
In approved flammable storage cabinets.
What type of gloves should be used when handling chemicals?
Chemical-resistant gloves appropriate for the substance.
What should you do before mixing any chemical?
Read the SDS and understand the hazards.
What is one requirement for eye wash stations in a lab?
They must provide at least 15 minutes of continuous flow.
Why is proper labeling of chemical containers critical?
To ensure correct handling and avoid accidental misuse.
What is the recommended maximum number of students per teacher in a lab?
24 students per teacher.
What should be done with outdated or unknown chemicals?
They should be properly disposed of as hazardous waste.
Why is it important to inspect chemical storage areas regularly?
To ensure containers are intact and chemicals are stored safely.
What training should teachers receive annually?
Training on chemical safety, PPE use, emergency procedures, and the CHP.
When should a fume hood be used?
When handling volatile, toxic, or corrosive substances.
What is a best practice for student lab behavior?
No horseplay or unauthorized experiments.
What should be included in a chemical inventory?
Chemical name, quantity, location, and date of receipt.
How often should emergency drills be conducted?
At least twice per year.
What is a common sign of chemical incompatibility?
