Chemical spills and cleaning
Most laboratory technicians store and handle hazardous materials which are flammable, reactive when in contact with air or water, corrosive or very toxic.

There are two main challenges to reduce laboratory accidents:

Develop accidental spill management on the one hand, and on the other hand cleaning of the equipment/material for the next use
However, the variety of chemical hazards often leads to the multiplication of equipment to attend all these various hazards. The response to the spill depends on the:
  • Chemical hazard, irritant, corrosive, reactive with water and air, explosive, oxidizing, flammable.
  • Toxic fumes that may be inhaled or cause irritation.
  • Damage to material, equipment, or building.
  • Discharges into the sewer system.


Materials and other equipment in laboratories should always be cleaned after each use. The surfaces should be decontaminated and rinsed/washed to avoid additional hazards.

How to absorb ammonia?

Ammonia is often used in its gaseous form. However, it dissolves readily in water, alcohols or other solvents in order to be used in an industrial setting or as a cleaning agent. An aqueous ammonia solution emits vapours that can irritate the respiratory system. If you wish to absorb and neutralize an ammonia spill, please follow these instructions :

  1. Evacuate the persons near the spill, protect yourself with the appropriate equipment and secure the zone.
  2. Make a dam around the spill with a neutralizing absorbent, such as TRIVOREX® versatile neutralizing absorbent (for all hazardous liquids) or BASICAPTAL® neutralizing absorbent(specifically for base spills). They will considerably reduce gaseous emissions, neutralize the basicity of the spill and allow you to collect the residue more easily.
  3. Put the absorbent on the spilled liquid. If the residue turns pink it is acid, when it turns back yellow, it is neutral.
  4. Collect the residue and remove the waste in accordance with the regulations in force.
How to neutralize the various types of chemical spills?

This procedure applies in the event of a minor spill that can be managed internally :

  1. Inform people in the vicinity of the hazard. Then find the right equipment to protect you and secure the area.
  2. Make a dam around the spill with TRIVOREX® neutralizing absorbent (compatible with all acids, bases, solvents, oxidants, etc.). It will reduce irritant vapours, neutralize the spill and allow you to pick up the residue more easily.
  3. Put the neutralizing absorbent on the spill and wait a few minutes for complete absorption of the liquid.
  4. Collect the residue and treat it in accordance with national regulations in force.
Is there a versatile solution that absorbs all liquid chemicals and neutralizes corrosives?

Managing a chemical, corrosive or irritant spill is a very dangerous task, difficult to pick up and thoroughly clean.

TRIVOREX® neutralizing absorbent (compatible with all acids, bases, solvents, oxidants, alcohols, etc.) will reduce irritant vapours, neutralize the spill and allow you to pick up residues more easily, regardless of their nature and concentration.
