Chemical Handling and Storage Questions and Answers Flashcards

What is the primary hazard when mixing calcium hypochlorite with an acid-based chemical?

Answer: Release of toxic chlorine gas

Mixing calcium hypochlorite with acids produces toxic chlorine gas, which can be lethal in enclosed spaces.

According to NFPA standards, what is the minimum separation distance between oxidizers and acids in a chemical storage room?

Answer: 20 feet or a physical barrier

NFPA requires at least 20 feet of separation or a non-combustible physical barrier between incompatible chemicals like oxidizers and acids.

What type of personal protective equipment is required when handling concentrated muriatic acid?

Answer: Chemical splash goggles, acid-resistant gloves, and a face shield

Concentrated muriatic acid requires chemical splash goggles, acid-resistant gloves, and a face shield due to its corrosive nature and fuming properties.

How should a CPO respond to a small chemical spill of granular calcium hypochlorite on a dry floor?

Answer: Sweep up carefully with a clean, dry broom into a clean, dry container

Dry granular calcium hypochlorite should be swept up carefully with a clean, dry broom. Adding water can cause a reaction, and acid would create toxic gas.

What information must be readily available to emergency responders at a pool chemical storage facility?

Answer: Safety Data Sheets (SDS) for all chemicals on site

Safety Data Sheets must be maintained on-site and readily accessible for all chemicals stored, as required by OSHA's Hazard Communication Standard.

What is the maximum recommended storage temperature for liquid sodium hypochlorite?

Answer: 60 degrees Fahrenheit

Sodium hypochlorite degrades rapidly at temperatures above 60 degrees Fahrenheit. Keeping it cool extends its shelf life and maintains available chlorine concentration.
