Spill Response Part 1: Assessing Risk and Retraining Instincts
This spill response series will address risk assessment, proper protection of responders, spill planning and training requirements, spill response techniques and decontamination of workers and equipment and reporting requirements.
During climactic scenes in action movies, the hero often runs into a burning building or other hazardous situation to rescue someone. As the building crumbles, they avoid gushing sprays of chemicals and burst through locked doors, disarm bombs and perform other miraculous feats. All while managing to rescue the victim and get them out of harm's way before the building collapses or explodes.
In real life, there are no stunt doubles or second takes. Rushing into a hazardous situation is often dangerous – even fatal. That’s why it’s essential for employees to recognize hazards and risks, and to be trained not to rush into a situation – even if they see an injured friend or coworker in the hazard area.
Overcoming Natural Instincts
When a child falls, a mother’s natural instinct is to rush to him, pick him up and comfort him. Trained medical personnel will tell you that this is the worst thing you can do, unless, of course, the child is in harm’s way and needs to be moved to prevent further injury. It is far better to let the child lay where he has fallen and determine the extent of injuries before moving him.
Contrast this instinct with what happens during sporting events: when an athlete goes down, the athletic trainers and medical technicians go to the athlete, but they have been trained to not move him until they have determined what is wrong and how he can be safely transported to avoid further injury. Even if it takes a while to determine the extent of the injury and the safest method of transportation, the time spent is essential to prevent further injury.
Workers need to be trained to take similar precautions when dealing with spills. While it is often impractical to train everyone at a facility to be a designated spill responder, all employees need to be aware of what to do when they see a spill.
Stop, Look and Listen
Children are sometimes taught to “stop, look and listen” as a safety precaution for crossing the street. The same maxim can be applied in spill response. At a minimum, train all employees to:
- STOP – Never walk through, taste or touch a spill. In addition, never rush into a spill area to help a worker who is injured or unconscious. If there is an unfamiliar smell in the air, don’t venture in to find the source.
- LOOK – How big is the spill? Can the source of the spill be located? Has a tank or container leaked? What equipment is in the spill area? Is the spill headed for drains or other sensitive areas?
- LISTEN – are there any unusual sounds, such as a burst feed line or a pressure valve that has released?
After taking a moment to observe the situation, what should workers be trained to do next? Should they pull an alarm? Alert a supervisor? Put up barricade tape? Determining what steps are to be taken, and training workers on their specific roles in spill response will help keep all employees safe. It will also help ensure that the appropriate actions are taken by those who are trained to handle the situation.
Even for office workers who – some would say – aren’t likely to ever see a spill, training is important. Their only action may be to leave the building and walk to a designated area when they hear an announcement over the intercom. However, unless they are trained on which exit route to take, where the designated meeting area is, and whom they need to report to once they are there, chaos could ensue in an actual emergency. For employees with limited spill responsibilities, this training can sometimes be coordinated with HazCom training, when employees are taught about the hazards in their workplace [29 CFR 1910.1200].
If employees will be more actively involved in emergency spill operations that extend beyond the scope of their normal work duties, or will clean up spills outside of their immediate work area, safety and awareness training can often be incorporated at the beginning of HAZWOPER training [40 CFR 1910.120].
Employees who regularly work in spill-prone areas should receive more in-depth training than just noting the location of the nearest exit. This training may include:
- Taking defensive actions, such as surrounding the spill area with absorbents or dikes.
- Emergency shutdown procedures
- Looking for fire hazards
- Identifying containers or tanks by UN number, placards or other markings
- First aid, CPR and defibrillator training
Assuming the Worst
When the nature of the spill cannot be determined, assume that the puddle – or lake – is the worst thing that could possibly have spilled at the facility. So, if the nastiest chemical at the facility is used oil, responders probably don’t need fully encapsulated suits and supplied air respirators. The color of the spill, its location or a penetrating smell may help in determining its severity.
When preparing spill plans and training onsite responders, use Safety Data Sheets (SDSs) to determine what hazards are present at the facility and what precautions may need to be taken. SDSs can help determine, among other things:
- What materials are actually onsite and need to be accounted for
- If the spill needs to be handled very quickly to prevent further hazards
- If the facility should be evacuated to avoid inhalation of noxious fumes
- Any health hazards
- Any fire or explosion risks
- Whether the spill will react with other materials
If the contents of a spill cannot be determined, instruments such as gas detectors, pH paper, etc. can be used – after responders are properly protected, of course – to help determine what the spill may actually be.
Putting it Together
Taking the time to determine the full extent of spill risks at a facility is a noble achievement, but if no one knows what to do during an emergency, these efforts have been wasted. If, for example, vapors from the spill are an inhalation hazard, precious time could be spent looking for people who have safely made it to an accumulation point and just haven’t checked in – or worse, people could have remained in the building and dismissed warning sirens or announcements as “just another drill.”
Planning and training everyone to know exactly what to do in a spill emergency will help keep everyone safe, and help speed response efforts by ensuring that life safety needs have been met prior to mitigation of a spill. Although environmental fines can be great if spills enter the environment, loss of life would be a worse tragedy.
