SECTION 4. FIRST AID MEASURES General Advice Show this safety data sheet to the doctor in attendance. Immediate medical attention is required. Eye Contact Rinse immediately with plenty of water, also under the eyelids, for at least *5 minutes. Immediate medical attention is required. Keep eye wide open while rinsing. Skin Contact Wash off immediately with soap and plenty of water while removing all contaminated clothes and shoes. Call a physician immediately. Inhalation Remove to fresh air. If not breathing, give artificial respiration. Call a physician or poison control center immediately. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Ingestion Immediate medical attention is required. Do NOT induce vomiting. Drink plenty of water. Never give anything by mouth to an unconscious person.
Most important symptoms and effects Causes burns by all exposure routes. Ingestion causes severe swelling, severe damage to the delicate tissue and danger of perforation: Product is a corrosive material. Use of gastric lavage or emesis is contraindicated. Possible perforation of stomach or esophagus should be investigated Self-Protection of the First Aider Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and prevent spread of contamination. Notes to Physician Treat symptomatically.
SECTION 5. FIRE-FIGHTING MEASURES Suitable Extinguishing Media Substance is nonflammable; use agent most appropriate to extinguish surrounding fire. CO 2, dry chemical, dry sand, alcohol-resistant foam. Extinguishing media which must not be used for safety reasons No information available. Specific Hazards Arising from the Chemical The product causes burns of eyes, skin and mucous membranes. Protective Equipment and Precautions for Firefighters As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. Thermal decomposition can lead to release of irritating gases and vapors.

SECTION 6. ACCIDENTAL RELEASE MEASURES Personal Precautions Use personal protective equipment as required. Evacuate personnel to safe areas. Avoid contact with skin, eyes or clothing. Environmental Precautions Should not be released into the environment. Do not allow material to contaminate ground water system. Do not flush into surface water or sanitary sewer system. Methods for Containment and Clean Up Sweep up and shovel into suitable containers for disposal. Avoid dust formation. Refer to protective measures listed in Sections 8 and *3. SECTION 7. HANDLING AND STORAGE Handling Wear personal protective equipment/face protection. Do not get in eyes, on skin, or on clothing. Use only under a chemical fume hood. Do not breathe dust. Do not ingest. If swallowed then seek immediate medical assistance. Storage Keep containers tightly closed in a dry, cool and well-ventilated place. Corrosives area. Store under an inert atmosphere. Protect from moisture. Specific Use(s) Use in laboratories  SECTION 8.

MDHS*4/3 General methods for sampling and gravimetric analysis of respirable and inhalable dust Exposure Controls Engineering Measures Use only under a chemical fume hood. Ensure that eyewash stations and safety showers are close to the workstation location. Wherever possible, engineering control measures such as the isolation or enclosure of the process, the introduction of process or equipment changes to minimise release or contact, and the use of properly designed ventilation systems, should be adopted to control hazardous materials at source. Personal protective equipment Eye Protection Hand Protection Glove material Goggles (European standard - EN **6) Protective gloves Breakthrough time Glove thickness Neoprene See manufacturers recommendations EU standard EN **4 Glove comments (minimum requirement) Inspect gloves before use. Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. (Refer to manufacturer/supplier for information) Ensure gloves are suitable for the task: Chemical compatability, Dexterity, Operational conditions, User susceptibility, e.g. sensitisation effects, also take into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion. Remove gloves with care avoiding skin contamination. Skin and body protection Respiratory Protection Large scale/emergency use Small scale/Laboratory use Long sleeved clothing When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. To protect the wearer, respiratory protective equipment must be the correct fit and be used and maintained properly Use a NIOSH/MSHA or European Standard EN **6 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced Recommended Filter type: Particulates filter conforming to EN **3 Use a NIOSH/MSHA or European Standard EN **9:***1 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. Recommended half mask:- Valve filtering: EN**5; or; Half mask: EN**0; plus filter, EN **1 When RPE is used a face piece Fit Test should be conducted
Hygiene Measures Handle in accordance with good industrial hygiene and safety practice. Environmental exposure controls Prevent product from entering drains.
