Masson trichrome Reagent A

Remove to open air.

Remove contaminated clothing. Wash immediately with plenty of water. Wash contaminated clothing before using it again.

Remove contact lenses, if present. Wash immediately with plenty of water for at least 15 minutes, opening the eyelids fully.

Induce vomiting only if indicated by the doctor. Never give anything by mouth to an unconscious person, unless authorised by a doctor.

carbon dioxide, foam, powder and water spray.

None in particular.

HAZARDS CAUSED BY EXPOSURE IN THE EVENT OF FIRE. Do not breathe combustion products.

Use jets of water to cool the containers to prevent product decomposition and the development of substances potentially hazardous for health.

The product must not penetrate into the sewer system or come into contact with surface water or ground water.

Collect as much material as possible and eliminate the rest using jets of water.

Before handling the product, consult all the other sections of this material safety data sheet. Avoid leakage of the product into the environment. Do not eat, drink or smoke during use.

Keep the product in clearly labelled containers.

Do not eat, drink or smoke during use.

As the use of adequate technical equipment must always take priority over personal protective equipment, make sure that the workplace is well aired through effective local aspiration.

Protect hands with category Ill work gloves (see standard EN 374). The following should be considered when choosing work glove material: compatibility, degradation, failure time and permeability. The work gloves' resistance to chemical agents should be checked before use, as it can be unpredictable. The gloves' wear time depends on the duration and type of use.

Wear airtight protective goggles (see standard EN 166).

If the threshold value (e.g. TLV-TWA) is exceeded for the substance or one of the substances present in the product, use a mask with a type B filter whose class (1, 2 or 3) must be chosen according to the limit of use concentration. (see standard EN 14387). In the presence of gases or vapours of various kinds and/or gases or vapours containing particulate (aerosol sprays, fumes, mists, etc.) combined filters are required. Respiratory protection devices must be used if the technical measures adopted are not suitable for restricting the worker's exposure to the threshold values considered. The protection provided by masks is in any case limited. if the substance considered is odourless or its olfactory threshold is higher than the corresponding TLV-TWA and in the case of an emergency, wear open-circuit compressed air breathing apparatus (in compliance with standard EN 137) or external air-intake breathing apparatus (in compliance with standard EN 138). For a correct choice of respiratory protection device, see standard EN 529.

Wear category I professional long-sleeved overalls and safety footwear (see Directive 89/686/EEC and standard EN ISO 20344). Wash body with soap and water after removing protective clothing.

The emissions generated by manufacturing processes, including those generated by ventilation equipment, should be checked to ensure compliance with environmental standards.

The product is stable in normal conditions of use and storage.

There are no particular risks of reaction with other substances in normal conditions of use.

No hazardous reactions are foreseeable in normal conditions of use and storage. HYDROCHLORIC ACID: risk of explosion on contact with alkaline metals, aluminium powder, hydrogen cyanide, alcohol.

None in particular. However the usual precautions used for chemical products should be respected.

alkalis, organic substances, strong oxidants and metals.

above decomposition temperature hydrochloric acid fumes may develop.
