How do I choose the right spill kit size?

Start with the largest likely single-container loss, check the type of liquid, then consider drains, watercourses, indoor or outdoor use and the workplace setting. SERPRO's calculator gives a practical starting recommendation, but the final choice should be checked against the site risk assessment and SDS.

Which absorbent type should I use?

Oil and fuel absorbents are normally used for hydrocarbons, chemical or hazmat absorbents for hazardous or corrosive substances, and general purpose absorbents for many everyday non-aggressive workplace fluids. Always check the SDS where the liquid is hazardous or unknown.

Does a spill kit replace secondary containment?

No. A spill kit is response equipment. It does not replace suitable storage, bunding, drip trays, site procedures, staff training or any legal requirement for secondary containment.
