Sorbents: The First Line of Defense Against Spills
Discover how oil-only, universal, and chemical sorbents keep workplaces safe and compliant, from everyday leaks to emergency spill response.
Sorbents are materials designed to absorb spilled liquids. Depending on the type, sorbents can be used for everyday maintenance tasks, such as catching leaks and drips, or in emergency response situations to contain larger spills. They are an essential part of workplace safety, compliance, and environmental protection.
Regulations to Consider
Sorbents are regulated under multiple safety and environmental standards:
OSHA 29 CFR 1910.22(a): Requires clean, dry, slip-free floors in the workplace.
EPA 40 CFR 112.7(c): Identifies sorbents as an approved method to prevent oil spills from reaching waterways or groundwater.
Types of Sorbents
Caution: Some products labeled “Universal sorbents” are made with organic materials (cellulose, peat moss, corn cob). These are not safe for acids or caustics, as they can trigger dangerous chemical reactions.
How to Select the Right Sorbent
1
Identify the liquid you need to absorb:
Determine whether you need an oil-only, universal, or chemical sorbent.
2
Estimate volume:
Consider how much liquid you need to absorb. This determines weight (light, medium, heavy) and format (pad, roll, sock, etc.).
3
Assess strength requirements:
Sorbent pads and rolls that are going to be walked on or used to wipe down equipment need to be stronger and tougher than sorbents that are only being used on puddled liquids.
Typical Sorbent Applications
Pads
Under machines/workstations for leaks and drips; can also wipe down parts or equipment.
Sorbents for Emergency Spill Kits
Emergency response kits often include sorbents. When selecting a spill kit, consider:
1. Liquid type: Oil-only, universal, or chemical spill kit.
2. Capacity: Can your kit effectively handle your “worst-case discharge”?
3. Portability: Choose between portable (carryable), mobile (wheeled), or stationary kits depending on your facility's needs.
Disposal of Used Sorbents
Used sorbents must be disposed of properly. Sorbents do not neutralize or alter the liquid they absorb; the waste must be managed under the same regulations as the spilled substance. Always:
Refer to state and local disposal regulations.
Review the MSDS/SDS of the absorbed liquid before disposal.
