IAFF Training for Hazardous Materials: Technician©<br />
Student Text<br />
• If <strong>of</strong>fensive actions are necessary, what is the risk<br />
versus the benefit to the entry team? Other responders?<br />
The public? The environment?<br />
• What are the hazards if <strong>of</strong>fensive actions are not<br />
taken? For example, is there likely to be a pressure<br />
release, or a reaction between incompatible chemicals?<br />
• Can these hazards be controlled through <strong>of</strong>fensive<br />
tactics?<br />
• Can <strong>of</strong>fensive control be done safely? Is the material<br />
stable, and can it be continuously monitored?<br />
• Are you reasonably certain that your <strong>of</strong>fensive<br />
actions will have a positive outcome? For example,<br />
will you be able to patch a hole before the material<br />
leaks completely?<br />
Activity<br />
Mitigation<br />
If you decide that:<br />
• The situation warrents <strong>of</strong>fensive tactics, and<br />
• Your team has the necessary training and resources, and<br />
• All operations can be carried out safely, then:<br />
Proceed with the <strong>of</strong>fensive containment tactics. Such actions<br />
may include:<br />
• Uprighting leaking containers<br />
• Closing and tightening caps and lids<br />
• Repositioning a container so the level <strong>of</strong> the hazardous<br />
material is below the breach<br />
• Decreasing container pressure by closing/opening a<br />
valve, or shutting down a pumping system<br />
• Blanketing with vapor suppression agents, such as foam<br />
• Neutralizing a chemical by applying another chemical<br />
• Disposing <strong>of</strong> the hazardous material in place<br />
• Using clamps or pneumatic plugs to stop dome cover<br />
leaks<br />
• Plugging or patching small holes<br />
• Applying inflatable bandages, straps, absorbents, and/or<br />
wedges to larger leaks such as gouges and splits<br />
