Vaporized hydrogen peroxide (VHP) is a popular and efficient method of bio-decontamination. It’s used in a variety of commercial, institutional and industrial settings to decontaminate or sterilize sealed enclosures such as filling machines, barrier isolators, glove boxes and workbenches.
In construction and industry, some potential hazards visibly manifest, such as the risk of falls from heights. Others are more hidden. A confined space may not look dangerous, but workers perish each year because someone assumed the air inside was safe to breathe when testing would have revealed that is wasn’t.
ISHN recently visited Honeywell’s Industrial Life Safety Training Center/Customer Experience Center in Pasadena, TX, to get some first-hand fall protection training and updates on the company’s hearing protection and gas detection lines.
An Arizona Public Service (APS) employee was killed this week in a fire following an explosion in an underground electrical vault in downtown Phoenix. News sources say 41-year-old Ricardo Castillo died in the incident, which happened at approximately 10:30 p.m. on June 30. Another APS employee was able to escape the fire but suffered burn injuries to his hands and face.
Broadly speaking, a confined space is an area that is large enough for a worker to enter and do work, but that is difficult to get in and out of easily, and not designed or intended for regular occupancy.
IEEE, the Institute of Electrical and Electronics Engineers, recently produced a paper1 reviewing 100 years of research on shock and arc injuries. Going back, the first recognized hazard to workers was the shock hazard.
