Notes to Physician Treat symptomatically. SECTION 5. FIRE-FIGHTING MEASURES Suitable Extinguishing Media Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. Extinguishing media which must not be used for safety reasons No information available. Specific Hazards Arising from the Chemical Produce flammable gases on contact with water. 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. SECTION 6. ACCIDENTAL RELEASE MEASURES Personal Precautions Ensure adequate ventilation. Use personal protective equipment as required. Avoid dust formation. Environmental Precautions Should not be released into the environment. See Section 12 for additional Ecological Information. Methods for Containment and Clean Up Sweep up and shovel into suitable containers for disposal. Keep in suitable, closed containers for disposal. Refer to protective measures listed in Sections 8 and 13. SECTION 7. HANDLING AND STORAGE Handling Avoid dust formation. Wear personal protective equipment/face protection. Ensure adequate ventilation. Do not get in eyes, on skin, or on clothing. Avoid ingestion and inhalation. Handle under an inert atmosphere. Storage Keep from any possible contact with water.

MDHS14/3 General methods for sampling and gravimetric analysis of respirable and inhalable dust Exposure Controls Engineering Measures Ensure adequate ventilation, especially in confined areas. 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 Wear safety glasses with side shields (or goggles) (European standard - EN 166) Hand Protection Protective gloves Glove material Breakthrough time Glove thickness EU standard Glove comments Disposable gloves See manufacturers - EN 374 (minimum requirement) recommendations 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 Long sleeved clothing Respiratory Protection 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 Large scale/emergency use In case of insufficient ventilation, wear suitable respiratory equipment Small scale/Laboratory use Use a NIOSH/MSHA or European Standard EN 149:2001 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. When RPE is used a face piece Fit Test should be conducted Hygiene Measures Handle in accordance with good industrial hygiene and safety practice.
