A chemical spill response always should follow below procedure:
Notify the chemical spill response contractors / first responders. Barricade the area of the spill to prevent additional contamination and risk of additional damage. Always wear proper PPE for cleanup of spill. Use compatible absorbents and neutralizing agents to contain the spill. Collect the spill cleanup waste material in chemical compatible containers and label the waste in a compliant manner. Depending on the waste characterization of cleanup waste, dispose as hazardous, non-hazardous, or solid waste.
