The ‘Silent Killer’ – Why Annual H2S Retraining Saves Lives

Hydrogen Sulfide is one of the leading causes of gas-inhalation deaths in the United States.

Known as the “Silent Killer,” H2S is highly flammable and toxic, even at low concentrations. It can easily build up in low-lying areas and confined spaces, and can quickly overcome unprepared workers. According to OSHA, H2S is one of the leading causes of workplace deaths related to gas inhalation, with 60 recorded exposure-related fatalities between 2001 and 2010.

One of the best ways to ensure your workforce has the knowledge to recognize, avoid, and contain this deadly poison is annual H2S retraining.

It’s imperative that anyone with the potential for exposure to H2S is sufficiently trained to recognize and understand the hazards associated with this gas. To further focus on the reduction of H2S related deaths and injuries, ANSI/ASSP requires yearly retraining for all workers with potential exposure to the deadly gas.

What are the benefits of annual retraining?

First and foremost, annual refreshers save lives.

By cementing the fundamental measures needed to recognize and prevent H2S poisoning into your workforce, you can eliminate the sources of the gas when possible. If the source cannot be eliminated, workers will know how to control and contain the exposure with engineering controls, administrative controls, and safe work practices. Workers are also trained in which personal protective equipment is the most effective to prevent H2S poisoning, leading to a safer worksite and industry.

Retraining not only saves lives but keeps you compliant with federal guidelines.

The first step to remaining compliant with the updated ANSI/ASSP standard is to sign up for proper training – a course that meets standards while providing students with life-saving information. PEC’s industry-leading H2S Clear course, developed by industry experts, is a comprehensive and standardized program that covers everything from the buddy system and characteristics to personal protective equipment and work procedures.

Guard yourself and your workers against this deadly poison with annual H2S retraining.
