Covers, seals and barrier types

Whilst covers, seals and barriers all serve the same function, each one differs slightly in its approach and application. Below is a breakdown of how each type of drain blocker helps keep your drain temporarily sealed off whilst dealing with a spill in the workplace.

• Covers   -   As it sounds, drain covers are designed to be placed over your drain to block the drain directly.

• Seals   -   These are designed to effectively seal off drains to be airtight, to ensure no liquid can escape into the drain.

• Barriers   -   Usually shaped like a ring, a U or a square, barriers are placed around the drain to block off the area surrounding it, preventing harmful chemicals or substances from entering.

Considerations when choosing covers, seals and barriers

• Material - Various materials can be used to make covers, seals and barriers. Whilst they are usually plastic based such as polyurethane, it's important to check that the material of the cover, seal or barrier is resistant to the types of substances that pose a potential hazard if spilled in your work environment. Some covers, seals and barriers are manufactured from clay as this is an absorbent material; these tend to be single use only.

• Reusability - Not all drain seals, covers and barriers are reusable, so it's always best to consider whether a single use or reusable product is ideal for your workplace. Clay based products are often single use due to their absorbent nature and must be disposed of safely once the spill has been dealt with.
