Chemical spills: how to behave?

In case of accidental spill of chemicals such as corrosive or inflammable products and products hazardous to the environment, the following questions must be answered immediately:

  • Which chemical was spilt?
  • How dangerous is it?
  • How to protect oneself?
  • How to stop the chemical from spreading?
  • Which solution should be used to neutralize it and remove it?
  • How to clean and secure the area?
  • How to safely dispose of the chemical?

In case of emergency

  • The spreading of the chemical increases the risk of damage to the floor and material
  • You must manage the potential consequences such as contamination and dangerous reactions with other chemicals
  • The spreading of the chemical hazard hampers the intervention

Current solutions

  • Universal absorbents with no neutralizing potential. After absorption, residues remain corrosive and harmful and therefore they are still a hazardous material which is difficult to dispose of.
  • Specific absorbents intended to neutralize only one kind of products. Sometimes the nature of the chemical is not known. Moreover, the reactions of neutralization may be dangerous.

How to make sure that you will use the appropriate neutralizer in emergency?

Thanks to their sound experience in human decontamination, PREVOR laboratories have designed the universal neutralizing absorbent TRIVOREX® so that no incident becomes an accident!!!

TRIVOREX®

use TRIVOREX® on chemical spills the absorbent TRIVOREX® the absorbent TRIVOREX® is a powder the absorbent TRIVOREX® neutralizes chemical hazards

Something new to front accidental chemical spills due to all kind of liquid chemical product.

Created by PREVOR laboratories, TRIVOREX® is intended to fight against all kind of accidental spills with liquid chemical products : acids, bases, oxydizing agents, reducing agents, oils, hydrocarbons, …

Its working mechanism: a double action, at the same time on the absorption and on the neutralization of chemical products.

Where are located its major advantages?

  • In its polyvalent efficiency on the entire range of liquid chemical products and as a consequence on the elimination of error risks during the choice of the treatment
  • In another important advantage : its atoxicity perfectly without any hazard for the user and the environment, able to neutralize the chemical aggressiveness of products before being evacuated. Indeed, it ensures a complete conformity with the legislation.

Using TRIVOREX®
General instructions for using TRIVOREX®

stop the spill
sprinkle the whole spill with TRIVOREX®
blue for a spill of base
pink for a spill of acid
  1. Secure the area of spill. If necessary, evacuate the area.
  2. Prevent the spreading of chemical and stop the spill.
  3. Sprinkle the edge of the pool with TRIVOREX®.
  4. For spills of small or medium quantities of chemical, sprinkle the whole spill with TRIVOREX®.
  5. For larger spills, there are two options:
    • the first one is to use a pump to remove a part of the spilt product.
    • the second one is to sprinkle the whole pool with TRIVOREX®.
  6. TRIVOREX® absorbs the spill almost instantaneously.
  7. Depending on the nature of the chemical, the color indicators of TRIVOREX® may or may not react:
    • the mixture TRIVOREX®+chemical turns to blue for a spill of base
    • the mixture TRIVOREX®+chemical turns to pink for a spill of acid
  8. When TRIVOREX® reacts, the mixture TRIVOREX®+chemical turns back to the initial yellow-green color. If this phenomenon isn’t visible, add more TRIVOREX® or a few milliliters of water to trigger the reaction of neutralization.
  9. If there is a risk of gas emission due to the addition of water, collect the mixture TRIVOREX®+chemical in order to perform neutralization in an area ventilated by hoods.
  10. When the mixture TRIVOREX®+chemical turns back to the initial yellow-green color, dispose of the solidified residues in accordance with the protocol in force in the firm.
  11. Now the residue is harmless and may be easily transported under its solid form.

    TRIVOREX®+chemical turns back to the initial yellow-green color dispose of the solidified residues

The steps in the use of TRIVOREX®

chemical spill the mixture turns pink for acid the mixture turns blue for base the mixture solidifies after neutralizing the chemical

pH indicator

TRIVOREX® neutralizes acids as well as bases

When neutralization of the chemical is complete, the pH indicator turns to blue for bases and to pink for acids, the product is solidified.

  • Sprinkle the area around the spill with TRIVOREX® to prevent the chemical from spreading.
  • Sprinkle the spill with TRIVOREX®
  • When TRIVOREX® reacts with a base or an acid, the indicator turns to:
    • Blue for bases
    • Pink for acids (as above with hydrochloric acid).
  • TRIVOREX® gelifies and finally solidifies the initial liquid and, in the same time, neutralizes it (the color turns back to the initial yellow-green shade).
  • When solidified, dispose of the residue in accordance with the applicable regulation.

Tested products

absorbent TRIVOREX®
  • Before and after use, TRIVOREX® is harmless to man and to the environment!
  • TRIVOREX® absorbs any chemical and neutralizes both acids and bases.
  • Because there are so many substances, TRIVOREX® hasn’t been tested on every chemical product but only on the ones presenting the characteristic hazards of their chemical family.
  • To try TRIVOREX® there are two options:
    • We can visit you to test TRIVOREX® on one chemical among the products listed below!
    • Our laboratory can test the efficacy of TRIVOREX® on any other substance. Please ask your customer advisor!
  • TRIVOREX® isn’t toxic if inhaled (oral DL 50 in rat > 2000mg/Kg).
