Module Six. Emergency Response. What to do in the first minute when the plan breaks. Every module before this one assumed the plan holds. This one is for when it does not. The unknown drum. The sudden release. The fire. The injury. Here is what we will cover. The first minute, and the fixed sequence. Sizing up from a safe distance. Unknown chemicals and drums. Spills and releases. Fire, explosion, and reactivity. Medical emergencies and exposure. And how we evacuate, account for everyone, and report it.
The first minute. Stop. Isolate. Notify. Do these three in order, before anything else. Stop means stop working. Stop the machine if it is safe to reach. Do not walk toward the problem. Isolate means move people back and keep them back. Put distance and a barrier between the hazard and everyone else. And notify means call it in immediately. Do not wait to be sure. Do not wait to fix it first. A response started one minute late is a much larger problem. The first minute is not for solving the problem. It is for not making it worse.
Size up. From a safe distance, upwind and uphill. You cannot run an incident from inside it. Get to a position where you are upwind of the release, and uphill if there is liquid, so anything that spreads runs away from you. From there, you look for four things. What is the substance, if you can tell safely. How big is the release. Is anyone hurt or trapped. And what is it threatening. Notice if you are downwind by the smell or the drift, and move. Read the scene from a distance, and let the people with the equipment get close.
Unknown chemicals and drums. Treat every unknown substance and every unlabelled drum as hazardous. This is the rule that does the most work of any rule in this program. You do not open it. You do not tip it. You do not smell it. You do not move it. You do not take the lid off to see. An unknown drum is not a curiosity. It is an uncontrolled hazard until someone qualified says otherwise. If a container has a placard or a label, that label tells you how to treat it, and a hazard diamond tells you the kind of danger in red, blue, yellow, and white. If there is no label, or you cannot read it, it is unknown, and unknown means hazardous. Isolate it, keep everyone away, and get it reported.
Spills and releases. Stop the source only if you can do it safely, and only if you are trained and equipped for that substance. If you are not, your job is distance, not containment. Never use water on a spill unless you know what the substance is and that water is safe. Water can spread a spill, or react with it, or turn a small problem into a large one. Do not let a spill reach a storm drain, a drain, a creek, or the ground. Those routes take it off the site and into a bigger problem. Contain what you can from a safe position, keep people back, and let the plan and the responders take it from there.
Fire, explosion, and reactivity. Some substances burn, some feed a fire, and some react violently with water or with each other. Flammables and solvents catch easily. Oxidizers make a fire burn hotter and faster. And water-reactive materials can erupt when water reaches them. Fight a fire only when it is small, incipient, and you have the right extinguisher and a clear way out. Otherwise, evacuate, and let the fire service handle it. Never fight a fire that is between you and your exit. Never fight a fire you do not understand. And never put water on a burning unknown. The safest call on an unknown fire is to leave it, and pull everyone back.
Medical emergencies and exposure. Someone down in a hazard area is the hardest call on any job, because the instinct is to run in. Do not become a second casualty. A rescuer who goes in unprotected usually becomes the next patient, and now the responders have two people to save. If you can reach the person safely, and only then, get them out, and move them upwind and away. If you cannot reach them safely, keep everyone back, and tell the responders exactly where the person is and what they were exposed to. Once the person is in a safe area, decontaminate before you treat, so the contamination does not move onto them or onto you. Then treat, and call for medical help early.
Evacuation and the muster point. When the call is to leave, leave, and go where you are told. Move upwind and uphill, away from the release, to the muster point. The muster point is not a suggestion. It is how we know who is safe. When you get there, report in, and stay there until you are accounted for and released. If the air itself is the hazard, and there is no time or no safe route to leave, then shelter in place. Go inside, close the doors and windows, shut down the ventilation, and wait for instructions. Either way, the count is the point. Everyone accounted for, or someone goes back in to look.
Reporting and after-action. Report the incident immediately, and report it straight. What happened, where, what the substance was if you know, who was involved, and who is hurt. Do not clean up to hide it. Do not tidy the scene before it is documented. Do not leave anything out because it looks bad. The report is how the company protects the next crew, and how it protects you. After the incident, take part in the review. What worked, what did not, and what we change. An incident that is reported honestly makes the whole program better. An incident that is hidden just waits to happen again.
Roles and the call. In the first minute, everyone has one job. One person calls nine one one, and gives the location, what the substance is if it is known, how much, whether anyone is hurt, and your name and call back number. Stay on the line until they tell you to hang up. One person holds the perimeter, and keeps people and traffic back. One person meets the responders when they arrive, and tells them what they know. And everyone else moves to the muster point, and stays accounted for. Nobody freelances. The plan works because each person does their one job.
The rules that hold. A handful of rules do the work in an emergency. Stop, isolate, and notify, in that order. Treat every unknown substance and drum as hazardous. Never approach, open, tip, smell, or move it. Do not become a second casualty. Never put water on a burning unknown. Evacuate upwind, and account for everyone. And report it straight, every time. When the plan breaks, fall back on the rules. They are short on purpose, because in the first minute there is no time to think.
Recap. Five points to carry to the next job. One. Stop, isolate, notify. That order, every time. Two. Size up from a safe distance, upwind and uphill. Do not approach. Three. Every unknown substance and drum is hazardous. Never open, tip, smell, or move it. Four. Do not become a second casualty. Decontaminate before you treat, and call for help early. Five. Evacuate to the muster point, account for everyone, and report it straight. That closes the program. Hazard recognition, site assessment, toxicology, protective equipment, decontamination, and emergency response. What holds it together is the same few rules, applied every day, on every job.
