How do you handle pyrophoric chemicals?
Gloves must be worn when handling pyrophoric chemicals – flame retardant gloves should be used when handling most of these in general laboratory settings. A Safety Data Sheet (SDS) should be reviewed if handling may involve extended or high exposures to lab personnel to ensure adequate protection is provided.
How is flammable waste disposed of?
