SECTION 2: Hazards identification

No toxic effects would be expected from inert solid form. Inhalation of metal dust and fumes may result from EFFECTS OF OVEREXPOSURE further processing of the material by the user, particularly during welding, burning, cutting, grinding and machining activities Short-term intensive exposure to dust may result in ACUTE irritation to eyes, mucous membranes and respiratory tract. Steel recently produced may be extremely hot. CHRONIC Sever pneumonitis, pulmonary disease NTP: nickel, chromium CARCINOGENIC IARC: nickel, chromium OSHA: none SIGNS AND SYMPTOMS OF EXPOSURE Nausea, tightness of chest, fever, irritation of eyes, nose, throat and skin.

Medical Conditions Generally Aggravated by Exposure

Chronic lung disease, allergic conditions. EMERGENCY AND FIRST AID Standard first aid procedures – remove to fresh air. PROCEDURES PRECAUTIONS FOR SAFE HANDLING AND USE STEPS TO BE TAKEN IN CASE OF RELEASE N/A OR SPILL WASTE DISPOSAL METHOD Material should be reclaimed for re-use; follow local, State and Federal solid waste disposal requirements. CONTROL MEASURES RESPIRATORY PROTECTION Dust/fume respirator. LOCAL EXHAUST As required to meet PEL. PROTECTIVE GLOVES As needed based on operations EYE PROTECTION As needed OTHER PROTECTIVE CLOTHING OR May be needed for grinding. Heat resistant face EQUIPMENT protection, clothing, boots and/or gloves may be necessary. The information contained herein is based on the data available to us and is believed to be correct.

PNA Square Dowel MSDS PRODUCT INFORMATION PRODUCT NAME: PNA Square Dowel clip PRODUCT TYPE: ABS plastic COMPANY CONTACT: PNA Construction Technologies, Inc. 9 Dunwoody Park, Suite 111 Atlanta, GA 30338 800.542.0214 COMPOSITION / INFORMATION ON INGREDIENTS CHEMICAL NAME: Acrylonitrile-butadiene-styrene Resin ; % 90 – 99% SYNONYMS: ABS CAS REGISTRY NO.: 9003 – 56 – 9 MAY ALSO CONTAIN: Mineral Oil 0-2% Tallow 0-2% Wax 0-2% Styrene monomer 2,000 ppm max Ethylbenzene 1,500 ppm max EYE Solid or dust may cause irritation or corneal injury due to mechanical action. SKIN Essentially nonirritating to skin. Mechanical injury only. Skin absorption is unlikely due to physical properties. Single dose oral toxicity is considered to be low. No INGESTION hazards anticipated from swallowing small amounts incidental to normal handling operations. Dust may cause irritation to upper respiratory tract (nose and throat). At room temperature, exposure to vapors INHALATION are unlikely due to physical properties; normal processing temperatures may generate vapors which may cause irritation if ventilation is inadequate. SYSTEMIC (OTHER TARGET ORGAN) Additives are encapsulated in the product and are not EFFECTS expected to be released under normal processing conditions or foreseeable emergency. PNA Square Dowel clip MSDS This mixture contains a component(s) which are listed as potential carcinogens for hazard communication purposes under OSHA Standard 29 CFR 1910.1200. Components listed by IARC: styrene monomer. An increase incidence of lung tumors was observed in mice from a recent inhalation on styrene. The relevance of this finding to humans is epidemiology studies of workers exposed to styrene do not provide a basis to conclude that styrene is carcinogenic. The very small quantities of

Cancer information

monomer, as indicated in Section 2, are not expected to cause any hazardous condition because of the low concentration in the resin. As the resin is supplied, monomer is not likely to be released into the surroundings in toxicologically significant amounts. Monomer may be released during processing of the resin and the hazard may vary from negligible to very low depending on actual exposure conditions. Ethylbenzene has been shown to cause cancer in laboratory animals. TERATOLOGY (BIRTH DEFECTS) No relevant information found. REPRODUCTIVE EFFECTS No relevant information found. FIRST AID EYE Flush eyes with plenty of water; mechanical effects only. SKIN No adverse effects anticipated by this route of exposure incidental to proper industrial handling. INGESTION If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by medical personnel. INHALATION Remove to fresh air if effects occur. Consult a physician. NOTE TO PHYSICIAN No specific antidote. Supportive care. Treatment based on judgment of physician in response to the patient. .
