Chemical Hazards - SPF/Isocyanates | Fire | Confined Spaces | Falls | Medical and First Aid | Electrical | Respiratory Protection | Personal Protective Equipment | Ventilation
Workers entering into confined spaces may be entering into areas that could have accumulated hazardous gases or that can become low oxygen environments, which can pose a risk for asphyxiation. In addition, isocyanates and other agents contained in the SPF are potentially flammable and present a fire hazard when used in spaces that are not properly ventilated. For example, the improper use of SPF in a confined space led to a fire in Falmouth, Masachussetts (May 2008) when a worker was trapped in an attic space and died. The worker was installing SPF insulation in the attic and did not have proper ventilation or an escape route. In addition, workers can be exposed to mechanical or electrical equipment inside confined spaces. Some of the areas that workers enter inside a construction/retrofitting site may be considered confined spaces.
