There are three main types of confined space hazard: atmosphere, engulfment or trapping. A hazardous atmosphere can be one that's depleted of oxygen, one with toxic gases like hydrogen sulfide or one with flammable gases like methane. Engulfment is when a substance like water or sand can inundate workers, suffocating or crushing them. Trapping occurs when the configuration in a confined space allows for workers to be stuck within the space. All of these hazards can be controlled and avoided through proper procedure and personal protection equipment.
Following a confined space safety program keeps employees protected from hazards. To help sewer inspection crews recognize the extreme risks of confined space entry, and to acquaint them with all the prerequisites for safe and legal confined space entry, Envirosight is offering a FREE Confined Space Safety poster.
