Hazard pictograms

Alert Words: Danger TASS-21D151 (2/9) Hazards information: Impediment of lungs by long-term or repetition exposure. When the product is heated to a high temperature, solvent gas may be generated. May cause harmful influence with long term exposure for skin. May cause mild irritation with hypersensitive person even with a brief contact. Contact with molten solder may result in severe burns. Decomposed gas may be irritant to the eyes. Decomposed gas may be irritant to nose, throat and lung and may cause breathe difficulty. Cause damage to digestive organ. Ingestion while vomiting may damage lung. Causes serious eye irritation. Causes damage to organs. Toxic to aquatic life Toxic to aquatic life with long lasting effects Caution: 【Safety Measure】 Obtain special instructions before use, or do not handle until all safety precautions have been read and understood. Do not eat, drink or smoke while using. Use outside or an area with good ventilation only. Do not inhale dust, steam, spray, gas, mist, vapors or fumes. Wash hands and contaminated parts carefully after use. Avoid emitting to the environment. Contaminated work clothing should not be allowed out of the workplace. Use personal protective gloves, glasses and mask as required. In case of inadequate ventilation, wear respiratory protection (as specified by the manufacturer/supplier or the competent authority). Wash contaminated clothing before reuse. Collect spillage. 【First aid】 In case of inhaling, move sufferers to place filled with fresh air, and let repose with posture easy to breath. If having indisposition, arrange for transport to nearest medical facility for examination and treatment by a physician. If on skin: wash with plenty of soap and water. If skin irritation or rash occurs: get medical advice/attention. If get into eyes: gently rinse the affected eyes with clean water, in case of wearing contact lens, better to remove them. Continue rinsing. If constant eye irritation: receive medical treatment. If chemical exposure or its risk: receive medical treatment.
