   Topic: Flammable Liquids

   • Overview of the OSHA Standard
   • This standard applies to the handling, storage and use of flammable liquids with a flashpoint at or below 199.4 degrees F (93 degrees C). There are two primary hazards associated with flammable liquids: explosion and fire. In order to prevent these hazards, this standard addresses the primary concern of design and construction, ventilation, ignition sources and storage.
   • Step 1: Planning the Lesson

   • 2. Complete the following optional topics:
   • a.
   • b.
   • c.
   • 3. Present Flammable Liquids to [number] participants

   • 6. Ensure feedback from participants at various points in the training
   • Guest Speakers/Presenters and Topics/Responsibilities
   • Step 2: Presenting the Lesson
   • Lesson Introduction
   • Introductory remarks or transition from previous lesson
   • Learning Objectives/Outcomes
   • Given an introduction to flammable liquids, participants will be able to:
   • 1. Define flash point and flammable liquid
   • Possible responses
   • The flash point is the minimum temperature at which a liquid gives off vapor within a test vessel in sufficient concentration to form an ignitable mixture with air near the surface of the liquid
   • Flammable liquids means any liquid having a flashpoint at or below 199.4 degrees F (93 degrees C)

   • 2. Explain two ways to avoid explosion or fire.
   • Possible responses
   • Practice safe handling, storage, fire control and ventilation
   • Ensure flammables are properly stored
   • Always handle and transfer flammable liquids using proper containers; or through proper transfer systems that employ a safety faucet, a safety pump, or a closed piping system
   • 3. Explain four potential sources of ignition.
   • Open flames
   • Smoking
   • Static electricity
   • Cutting and welding
   • Hot surfaces
   • Electrical and mechanical sparks
   • Lightning
   • 4. Identify actions that apply to the good plan for safe use of flammable liquids
   • Control of ignition sources
   • a. Identify sources of ignition
   • b. Always use bonding and grounding when transferring flammable liquids into/from containers
   • c. Always provide adequate ventilation to reduce the potential for ignition
   • Proper Storage
   • a. Identify compatible chemicals
   • b. Isolate and separate incompatible materials
   • c. Ensure storage doesn’t limit safe egress
   • d. Store in proper area, cabinet, or container
   • e. Label storage areas/cabinets
   • f. Store waste and residue in covered containers and dispose of daily
3. Page 3
   • Fire Control
   • a. Ensure proper hoses, fire extinguishers or other fire control devices are available where flammable liquids are stored
   • b. Do not permit flames or smoking in areas where flammable liquids are stored
   • c. Store materials that react with water in a room separate from flammable liquids
   • Safe Handling
   • a. Carefully read the manufacturer’s label on the flammable liquid container before storing or using it
   • b. Practice good housekeeping in flammable liquid storage areas
   • c. Clean up spills immediately, and then place the cleanup rags in a covered metal container
   • d. Only use approved metal safety containers or original manufacturer’s container to store flammable liquids
   • e. Keep the containers closed when not in use and store away from exits or passageways
   • f. Use flammable liquids only where there is plenty of ventilation
   • g. Keep flammable liquids away from ignition sources such as open flames, sparks, smoking, cutting, welding, etc.
