Responding To Spills or Other Emergencies

Although smaller volumes of spray polyurethane foam (SPF) chemicals are used during low pressure applications than in high pressure applications, it is advisable to have an emergency spill containment kit available that contains absorbent materials such as clay, pads, or socks to contain or minimize the affected area. To help prevent spills, it is good practice to keep all containers of chemicals tightly sealed except when they are actually in use. If a spill does occur, all personnel should be directed away from the immediate area and those workers designated for spill clean-up should put on the appropriate PPE and clean the area.

The spilled material should be absorbed with sand, earth or absorbent clays and placed in drums. If MDI has been spilled, a neutralization solution can be used according to the SDS.  These drums should not be sealed for an appropriate period (typically, at least 48 hours).

Fires, spills, and other emergencies involving MDI require an immediate response by trained and knowledgeable personnel. If you have not been trained to respond to an emergency, leave the area immediately and notify the appropriate emergency response personnel. If you need additional guidance, CHEMTREC®, the Chemical Transportation Emergency Center, is available to provide assistance by telephone 24-hours a day in the event of an emergency involving a fire, leak, spill or personnel exposure, CHEMTREC's emergency number is 1-800-424-9300.
