• Avoid contact with skin and eyes.
• Avoid formation of dust and aerosols.
• Further processing of solid materials may result in the formation of combustible dusts.
• The potential for combustible dust formation should be taken into consideration before additional processing occurs.
• Provide appropriate exhaust ventilation at places where dust is formed.
• Keep away from sources of ignition - No smoking.
• Take measures to prevent the build up of electrostatic charge.
🏪 Storage Conditions
• Keep container tightly closed in a dry and well-ventilated place.
• Keep wetted with water.
• Do not allow material to become dry.
Exposure Controls & Personal Protective Equipment (PPE)
Occupational exposure limits, engineering controls, and required safety equipment
🏭 Engineering Controls
Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling the product.
🧤 Hand Protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Material: Nitrile rubber. Minimum layer thickness: 0.11 mm. Break through time: 480 min. Material tested: Dermatril® (KCL 740 / Aldrich Z677272, Size M). Tested according to EN374. If used in solution, or mixed with other substances, and under conditions which differ from EN 374, contact the supplier of the CE approved gloves.
👁️ Eye Protection
Face shield and safety glasses. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
😷 Respiratory Protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
🦺 Skin/Body Protection
Complete suit protecting against chemicals, Flame retardant antistatic protective clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
🌍 Environmental Exposure Controls
Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
Chemical Stability & Reactivity Data
Chemical stability, hazardous reactions, and incompatible materials information
✅ Chemical Stability
Stable under recommended storage conditions. Contains the following stabiliser(s): Water (>=30 - <= 40 %)
⚗️ Reactivity
No data available
⚠️ Hazardous Reactions
No data available
🚫 Conditions to Avoid
Picric acid forms salts with many metals some of which are rather sensitive to heat, friction, or impact, e.g., lead, iron, zinc, nickel, copper, etc., and should be considered dangerously sensitive. The salts formed with ammonia and amines, and the molecular complexes with aromatic hydrocarbons, etc, are in general not so sensitive. Contact of picric acid with concrete floors may form the friction-sensitive calcium salt. Dry mixtures of picric acid and aluminum powder are inert, but the addition of water causes ignition after a delay dependent upon the quantity added. Storage conditions: records of purchase dates should be maintained for each container. Material older than 2 years should be disposed. Inspect and add water every six months as needed. Rotate containers to distribute water every three months. Heat, flames and sparks.
