Hazard Communication

Core Safety — from the Anvil & Co. course library. What you will learn: • Read chemical labels and locate useful SDS sections. • Recognize exposure routes and select controls before use. • Respond safely to unknown containers, releases and changed hazards. Key points: • HazCom makes chemical hazards understandable before exposure. Construction 1926.59 applies the requirements of 1910.1200. The employer needs a written program, hazardous chemical inventory, labels, accessible SDSs and effective employee training. • Identify the chemicals used or generated by your work: fuels, adhesives, cleaners, coatings, welding fumes and silica-containing dust. Inhalation, skin or eye contact and accidental ingestion are exposure routes. Keep food and drinks away and wash before eating. • A shipped hazardous chemical label normally includes a product identifier, supplier identification, signal word, hazard statements, precautionary statements and pictograms. Match the product identifier to the SDS; do not rely on color or smell to identify a chemical. • Danger indicates more severe hazards than Warning, but a product without either word is not automatically safe. Pictograms identify types of hazard, not every safe-use instruction; read the complete label and SDS. • Recognize flame (fire hazards), corrosion (skin/eye burns or metal corrosion), skull and crossbones (severe acute toxicity), health hazard (such as cancer or respiratory sensitization), and exclamation mark (such as irritation). A cylinder warns of gases under pressure. Never guess PPE from a pictogram alone. • SDSs use a 16-section format. Start with section 1 for identity, 2 for hazards, 4 for first aid, 5 for fire, 6 for accidental release, 7 for handling/storage and 8 for exposure controls/PPE. Section 10 explains stability and incompatible materials. • Workers must have ready access to SDSs during each shift. Electronic access must not create a barrier during an emergency. Locate the real SDS system and backup method with your supervisor before using a chemical; this course does not supply your employer's inventory. • Workplace containers need an appropriate identifier and hazard information, or another permitted workplace labeling system. The portable-container exception is narrow: immediate use only by the person who transferred it. A container left for someone else or another shift does not qualify. Never put chemicals in drink bottles. • Do not use a chemical from an unknown or inadequately labeled container. Secure the area as appropriate, notify the supervisor and have the identity and hazards confirmed before use. Do not sniff, taste or mix it to find out what it is. • Select ventilation, substitution, closed handling and other controls before PPE. Follow SDS storage and incompatibility guidance. Do not mix cleaners, fuels or reactive chemicals unless a reviewed procedure specifically permits it. • Learn the site's methods for detecting releases, such as monitoring instruments, alarms and visible signs; smell is not a reliable detector. For a release, move to safety and report it. Only personnel with the required training, equipment and assigned duties may respond; awareness training does not authorize spill cleanup. • Training is needed at initial assignment and when a new chemical hazard is introduced. Employers must explain non-routine tasks and how contractors share hazard information. The 2024 HazCom revision has transition provisions; consult OSHA's current guidance rather than assuming every supplier label changes on the same date. Scenario: A cleaner is transferred into a spray bottle and left for the night crew. The bottle has no label. Explain why the immediate-use exception does not apply. Locate the original label and SDS, identify sections 4 and 8 and describe the safe next step without using the unknown bottle.
