Course Overview

What happens when you mix bleach with the wrong chemical? The answer could be deadly. Sodium and calcium hypochlorite—the active ingredients in everything from household bleach to industrial sanitizers—are powerful oxidizers that protect public health when used correctly but can cause serious injuries or fatalities when mishandled. The federal Occupational Safety and Health Administration (OSHA) provides strict requirements for chemical safety under the Hazard Communication Standard (29 CFR 1910.1200), Air Contaminants regulations (29 CFR 1910.1000), and Personal Protective Equipment standards (29 CFR 1910.132-138).

Every year, thousands of workers suffer chemical burns, respiratory damage, or worse from preventable hypochlorite incidents. These accidents often result from simple mistakes: mixing incompatible chemicals, using the wrong PPE, or responding incorrectly to spills. Do you know that combining hypochlorite with acids creates chlorine gas—the same poison used as a chemical weapon in World War I? Are you aware that calcium hypochlorite can spontaneously ignite when contaminated with organic materials like oil or grease? Can you recognize the symptoms of chlorine exposure, which may not appear until hours after contact?

This comprehensive training prepares you to work safely with these common yet dangerous chemicals. Whether you're a water treatment operator, healthcare worker, food processor, pool technician, warehouse handler, or anyone who encounters hypochlorite disinfectants, this course provides the knowledge and skills to protect yourself and your coworkers from preventable chemical injuries.

No Worries. Here’s Some Helpful Info.

What is the OSHA permissible exposure limit for chlorine gas?


OSHA sets the Permissible Exposure Limit (PEL) for chlorine gas at 1 part per million (ppm) as a ceiling limit, meaning this concentration should never be exceeded, not even momentarily. Most people can smell chlorine at 0.3 ppm, well below the danger level.


How should sodium hypochlorite be stored to maintain safety and effectiveness?


Store sodium hypochlorite in cool (below 70°F), dry, well-ventilated areas away from direct sunlight. Keep it segregated from acids, ammonia, and organic materials by at least 20 feet or physical barriers. Use only HDPE or polypropylene containers, never metal. The chemical degrades over time, losing approximately 20% strength per year.


What should you do if hypochlorite solution gets in your eyes?


Immediately flush eyes with lukewarm water for at least 15 minutes, holding eyelids open to ensure thorough rinsing. Remove contact lenses if possible, but don't delay flushing to do so. Seek medical evaluation even for minor exposures, as delayed effects can occur.


What toxic gases are produced when hypochlorite is mixed with other chemicals?


Mixing hypochlorite with acids (including vinegar) produces chlorine gas, which can cause severe respiratory damage or death. Mixing with ammonia creates chloramine vapors, which are equally toxic and potentially explosive. Never mix hypochlorite with any other chemical unless specifically directed by manufacturer instructions.


What industries commonly use sodium and calcium hypochlorite, and what are their main applications?


Water treatment facilities use bulk quantities for disinfection. Healthcare facilities use specific concentrations for surface disinfection and instrument processing. Food processors use FDA-approved concentrations (50-200 ppm) as no-rinse sanitizers. Swimming pools use calcium hypochlorite for water treatment. Each industry requires specific safety protocols based on concentration, volume, and application method.
