Frequently Asked Questions:
- When should I use a fire extinguisher?
You are not required to fight a fire. Ever. If you have the slightest doubt about your control of the situation DO NOT FIGHT THE FIRE.
Use a mental checklist to make a Fight-or-Flight Decision. Attempt to use an extinguisher only if ALL of the following apply:
*** The building is being evacuated (fire alarm is pulled)
*** The fire department is being called (dial 911).
*** The fire is small, contained and not spreading beyond its starting point.
*** The exit is clear, there is no imminent peril and you can fight the fire with your back to the exit.
*** You can stay low and avoid smoke.
*** The proper extinguisher is immediately at hand.
*** You have read the instructions and know how to use the extinguisher.
IF ANY OF THESE CONDITIONS HAVE NOT BEEN MET, DON'T FIGHT THE FIRE YOURSELF. CALL FOR HELP, PULL THE FIRE ALARM AND LEAVE THE AREA.
- How do I use a fire extinguisher?
Whenever possible, use the "Buddy System" to have someone back you up when using a fire extinguisher. If you have any doubt about your personal safety, or if you cannot extinguish a fire, leave immediately and close off the area (close the doors, but DO NOT lock them). Leave the building but contact a firefighter to relay whatever information you have about the fire.
Pull the pin on the fire extinguisher.
Stand several feet from the fire, depress the handle and sweep back and forth towards the fire. Note: Do not walk on an area that you have "extinguished" in case the fire reignites or the extinguisher runs out! Remember: you usually can't expect more than 10 full seconds of extinguishing power on a typical unit and this could be significantly less if the extinguisher was not properly maintained or partially discharged.
The metal parts of CO2 extinguishers tend to get dangerously cold -- practice using one beforehand or have someone show you the proper way to hold one.
Again, proper training is usually required by Workplace Safety and Health regulations.
Direct the extinguisher at the base of the flames until the fire is completely out.
Recharge any discharged extinguisher immediately after use.
- How do I maintain a fire extinguisher?
At least once a month (more often in severe environments) you should inspect your extinguisher. Ensure that:
a. The extinguisher is not blocked by equipment, coats or other objects that could interfere with access in an emergency.
b. The pressure is at the recommended level. On extinguishers equipped with a gauge, that means the needle should be in the green zone - not too high and not too low.
c. The nozzle or other parts are not obstructed.
d. The pin and tamper seal (if it has one) are intact.
e. There are no dents, leaks, rust, chemical deposits and other signs of abuse/wear. Wipe off any corrosive chemicals, oil, gunk etc. that may have landed on the extinguisher.
f. Some manufacturers recommend shaking your dry chemical extinguishers once a month to prevent the powder from settling/packing. We are dubious this has any value, but you are going to pick it up to inspect it anyway, so why not give it a good shake?
Fire extinguishers should be pressure tested (a process called hydrostatic testing) after a number of years to ensure that the cylinder is safe to use. Consult your owner's manual, extinguisher label or the manufacturer to see when yours may need such testing. If the extinguisher is damaged or needs recharging, get it replaced immediately!
One more time: Recharge all extinguishers immediately after use regardless of how much / little they were used.
- A variety of accidents could occur. Some are serious and others are minor. Which type of accident should I consider when selecting the correct header?
The ANSI Z535 standard states that you should use "Worst credible severity of harm if an accident occurs". In practice, this means that sign buyer might lean towards the conservative alternative when weighing various severity and injury likelihood scenarios. For example, choose DANGER instead of WARNING for a given hazard if there is only a small likelihood of a serious injury occurring.
- The header definitions seem to have precise definitions for both 'Will'(Danger Header) and 'Could' (Warning Header) in describing when to use a given header. Can you give me more detail here?
The ANSI Z535 definitions are as follows:
Will: Indicates an event that is expected to happen with near certainty.
Could: Indicates an event that is possible but not nearly certain.
- In looking over the differences in sign hazard levels, I am confused on how to best determine injury severity. Do you have any guidelines here?
ANSI defines serious injuries as those that typically have one or more of the following characteristics:
� results in permanent loss of function or significant disfigurement
� requires substantial and prolonged medical treatment
� involves long periods of disability
� involves considerable pain and suffering over long periods of time
- When should I use a Bilingual Sign?
A warning label or sign should try reach as wide an audience as possible. Without getting into official languages legislation, we recommend using a bilingual sign if there is a substantial non-English speaking audience that needs to be aware of the potential hazard.
Typically, the bilingual module is attached on the right or at the bottom of the label. It is important that a dual language sign not look cluttered. Too many languages make it hard to read.
- How large a sign should we order?
The ANSI Z535.2 sign standard uses a ratio of 25 feet of viewing distance per inch of text height, assuming favourable viewing conditions.
For unfavourable viewing conditions, (e.g. low light, cluttered area, distractions, etc.) this ratio lowers to 12.5 feet of viewing distance per inch of text height.
- Should I fasten my sign to the inside or outside of our fence?
It is far better to put the sign on the outside. That way the sign is most easily seen and read. With a strong fastening system, the sign is very hard to steal, even for professional scrap metal vandals. A sign on the inside of the fence is not as effective.
- What do I do in case of an oil or chemical spill?
1. Take action. It is imperative to take immediate action when a spill occurs. Make sure that the area is immediately secured and that only authorized people are at the scene of the accident.
Determine what has happened - what liquid has leaked out, approximately how much and call for help if required.
2. In case of hazardous spills, make sure to wear protective clothing! Make sure you are protected in a way so that you do not cause harm to yourself or others. Start by wearing protective clothing such as gloves, goggles, body suits, and breathing apparatus if required.
3. Minimize damage & stop further contamination. Try to prevent further contamination after finding out where the origin of the spill is. Take preventative methods to minimize further spillage if a drum has tipped over or a tank has a rupture. You can either plug the hole or move the leaking container in a way so that it no longer leaks or at least minimizes the problem.
4. Seal drains to contain the situation. In order to achieve this, you must first make sure that sufficient effective materials are available to do this. Mini-booms (SOC's) and drain-covers (SPC) and SPC Drain Plugs are very effective to contain a spill. If the spill is in the water, containment booms combined with sorbent booms are an effective way of preventing further spreading of the liquid at hand.
5. Begin clean-up. Using materials at hand, the clean up job can begin. Materials used could include sorbents in forms of pads, rolls, mini-booms, pillows, booms and sweeps. Other materials frequently used include skimmers when the spill is on water. For some spills, a loose weight absorbent could also be considered as useable.
6. Contact authorities. Authorities must be contacted when dealing with environmentally hazardous liquids such as chemicals, acids and petroleum-based liquids. The authorities can assist by deploying services such as fire departments, ambulances and conservation officers. The authorities will also be able to give good advice as to how to deal with the spill. It might also be a good idea to contact insurance companies if such policies are in place.
7. Dispose of used clean up materials according to local regulations. Make sure that the local regulations are followed when it comes to disposing of materials. Note that the sorbents take on the characteristics of the absorbed material. They should be disposed in a manner that is compatible with the disposal requirements for the spilled oil or chemical.
8. Re-stock clean up materials. It may not seem important at the time, but it will become very important if another spill occurs and there is insufficient material for containment and clean up. It is comparable to having a fire and not having a fire extinguisher at hand.
9. Review contingency plans and procedures. If you do not already have a contingency plan in place, you should consider preparing one. It is important to be prepared for "the worst". It is much easier to handle a chemical or oil spill if you are prepared with the proper materials and procedures.
- What confined space entry equipment do I need to comply with Workplace Safety and Health regulations?
The regulations don't provide a list of required equipment, but they do insist that the worker and the employer take all reasonable precautions to ensure the safety of the person entering a confined space.
Confined space work is very different than a confined space rescue. Confined space rescue is concerned with getting into a confined space quickly and safely, and then evacuating the confined space with a victim. Most fire departments and first responders have received this type of rescue training, and have specialized equipment to perform confined space rescues.
Confined space work, in the water and wastewater industry, very often entails entering a pit or manhole through a small access hatch or manhole lid. Confined space work allows time for planning the safest and most efficient means to perform the work. If done safely, confined space work should not require a confined space rescue. Having said that, the worker entering a confined space should always be prepared to be rescued should something go wrong (think heart attack or other medical emergency). At a minimum, a worker should always wear a harness so that he can be hoisted out of the pit quickly and with minimal risk to himself and / or his rescuers.
Water and wastewater workers should never work in an atmosphere that is known to be immediately dangerous to life and health. Always purge the confined space of dangerous gasses, and ensure that the source of dangerous gasses has been positively eliminated. SCBA equipment should be considered as your back-up plan. Unless you are part of a highly trained confined entry team familiar with SCBA equipment, SCBA should never be your primary source of air unless you are performing a rescue.
In general, a "permit" is required to enter a confined space. The permit is a checklist that has been developed by a professional who is familiar with all of the risks that might be reasonably expected to occur in that particular confined space at that particular time. The permit will list all of the possible risks, and will also list the equipment, the methods and the manpower necessary to allow a worker to work in the confined space safely. The permit is discussed and signed by both the worker and the supervisor prior to the worker entering the space.
Confined space equipment is not inexpensive, and it does require regular maintenance and replacement. Training, which includes periodic refresher courses, is required to maintain and use confined entry equipment.
CleanFlow Utility Supply Company carries a full line of quality confined space equipment that is ideal for water quality professionals. Feel free to call us to discuss your exact requirements.
- What are the three rules of gas detection?
1. Test: Before you use your instrument, it is important that you know that the sensor and alarms will function properly. The only way that you can be sure of this is to expose your instrument to a known concentration of gas and verify that it responds correctly. A bump test prior to each day's use assures you that your gas detector will save your life if you are in danger.
2. Calibrate: Conditions such as temperature, humidity, age and gas exposure will all affect the output of your sensor. Calibrating your instrument compensates for these factors and guarantees that your readings are accurate. You can attain the highest accuracy by calibrating your gas detector on a regular schedule. Do this at least on a monthly basis.
3. Review Data: Almost all gas detectors in use today provide some form of datalogging. Information stored in your gas detector can provide keen insight into potential dangers that may be hiding in your work environment. You may find cases of alarms with no reports or you may find conditions where gas concentrations exist just below the alarm thresholds of the instruments. Most data reviews take place only after an accident occurs. A weekly review of data gives you the opportunity to find potential danger points and correct them before tragedy strikes.
- I use my gas detector very infrequently. How often should it be calibrated?
Normally instruments should be calibrated with gas on a monthly basis. However, if they are not being used regularly, it may not be feasible to maintain them that way. In this case, the recommendation would be to calibrate them before use or monthly, whichever is less frequent. The idea would be only use the monitors if they have been calibrated within the last month. Of course, regardless of the calibration, the instruments should be bump tested prior to each use to ensure that they do respond to gas.
- Why do I have to perform a bump test my confined entry monitor before use?
The reason for the bump test is that actually applying gas to the sensors and verifying that they do respond is the only true way that you know for certain that the sensors will in fact respond to gas. If something happened to the monitor during or after the last time it was used, the only way that you would know that the unit is damaged is to test it with gas and verify that it responds.
- Do I need to take any special precautions while calibrating or bump testing my confined entry monitor?
There is no need for any equipment and any precautions other than calibrating the unit in a well ventilated area. The gas will dilute quickly in air to a level that is of no concern when it comes out of the bottle. The unpleasant smell is the only thing that you would have to worry about.
- How should I dispose of a calibration gas cylinder?
The calibration cylinders supplied by Industrial Scientific Corporation are disposable. These cylinders are DOT 39 or 2Q rated. This is the same classification used for home aerosol cans. This means that disposal may be performed by relieving the cylinder of any pressure and placing it in your waste disposal container. Check local regulations for compliance.
Some companies are required to dispose of these calibration cylinders as hazardous waste, either by company policies or by local regulations. If your company falls into this category, simply return the empty cylinders to Industrial Scientific.
