The use of engineering controls and monitoring equipment will go a long way in protecting your employees. But just like any other safety equipment, you must maintain them.

Calibrate personal monitors on a regular basis. For the most part, this means at least once every 30 days. Check the manufacturer’s recommendations for your particular monitor. You also need to make sure that the monitors are fully charged before putting them into use. Check the integrity and accuracy of your monitors by performing “bump tests” every day, or before each use.

Keeping your employees safe involves more than just providing them with PPE. Train them on the specific hazards of your industry. Teach them how to recognize high risk situations. Prepare them as best as you can for the dangers that come with the job. And don’t forget to review the dangers of these invisible, deadly gases often.
