OSHA Guidelines For Hazard Prevention

OSHA just released the first recommended practices list in more than twenty years. Is it something you need to know about?

 

Probably. But you probably don’t have a few hours to spend browsing their website for information.

 

Save yourself some time. Here’s a summary of the important parts, and links to get you to the ones you want to know more about.

 

  • GETTING STARTED

 

First off, here’s a quick guide to the process of implementing recommended practices:

osha guidelines

There are two areas of focus here: preparing and training people, and inspecting and improving facilities, equipment, and practices. If you need some more details, head to this link: https://www.osha.gov/shpguidelines/ten-easy-things.html

 

 

  • GETTING MANAGEMENT TO WORK WITH YOU

 

You’re going to have a hard time getting a safety program off the ground if management isn’t buying in. The OSHA guidelines recommend four basic steps below to make sure they’re with you:

If you need more details about things you should do to get management and leadership engaged, this is your place to look: https://www.osha.gov/shpguidelines/management-leadership.html

 

  • GETTING WORKERS INVOLVED

 

If getting your workers to be involved and serious about your safety program is a concern, here are OSHA’s suggested steps to make sure you have genuine worker investment:

osha-3

So what does it take to get workers to care about and want to participate in your safety program? And what are some of the barriers to their participation? If this is a topic you’re interested in, here’s the place to go: https://www.osha.gov/shpguidelines/worker-participation.html

 

  • HAZARD IDENTIFICATION, CONTROL, AND PREVENTION

 

Before you can do anything about hazards in your workplace, you have to find them. Not just the obvious ones, either: there may be hazards that only people who use a particular machine or work in a particular area are aware of, for example.

 

Once you’ve identified the hazards that need to be addressed, what do you do about them? You look for ways to control them, starting with the most dangerous or the ones that can be easily eliminated. Getting workers involved in deciding what controls you’ll use is also a great step to get them more active in the program.

osha-4

 

These are obviously the nuts and bolts of a safety program, but they don’t work if you haven’t gotten managers and workers on board and involved. Workers are probably the people most likely to know where the real hazards are and where things might go wrong, but they’re not likely to want to talk about it with management you’ve established a program where reporting a hazard is encouraged, not punished.

 

If hazard identification is your topic, check here: https://www.osha.gov/shpguidelines/hazard-Identification.html

If you’re moving past identification and ready to tackle prevention and control, this is your destination: https://www.osha.gov/shpguidelines/hazard-prevention.html

 

  • EDUCATION AND TRAINING

 

You can have a great program, but if nobody knows what they’re supposed to do or who is supposed to handle what part, you’re not going to get anywhere. Here’s the very basic breakdown:

osha-5

 

OK, you’re probably going to need to get a little more in-depth than this. Fortunately, OSHA has some handy resources available, including training tools to help people get better at spotting hazards: https://www.osha.gov/shpguidelines/education-training.html

 

  • PROGRAM EVALUATION AND IMPROVEMENT

So you started a program, and you got everyone to participate, and things seem to be going really well. Or perhaps your program, for whatever reason, isn’t doing what you hoped it would do. Evaluation is the part where you figure out what’s going well and what’s not. And improvement is the part where you do more of what’s working and less of what isn’t.

 

osha-6

If you’re working on a safety program and need to be able to report on how it’s going and what it’s doing for the company, check out OSHA’s suggestions and tools for figuring it out: https://www.osha.gov/shpguidelines/program-evaluation.html

 

 

 

There’s your very quick summary of OSHA Guidelines and Recommended Practices! If you need lots and lots more information, OSHA makes sure you have tons of links and helpful tools to check out on their “additional resources” page here: https://www.osha.gov/shpguidelines/program-evaluation.html.

 

As always, if you are looking for dust and fume collection or fire and explosion safety controls, we are here to help you with any information you need. This equipment is usually considered best practice for dealing with combustible dust, including spark arrestors, abort gates, and fire retardant dust collector filters.

 

(DISCLAIMER: This guide is not intended to be used in place of OSHA guidelines or actual recommendations. We hope it helps you get an overview of what’s available, but while we are dust and fume collection experts, we defer to those more knowledgeable when it comes to safety program design)

Spark Trap Safety System: Protect your Dust Collector

Extinguish the threat of explosions with a Spark Trap safety system.

While it is imperative that every metalworking facility have highly efficient dust collection systems, it is just as crucial that metalworking facilities utilize a spark trap safety system to provide even greater protection from these combustible hazards.

spark trap safety systemWe have dedicated over a 15 years to preventing and reducing fires and explosions in metalworking and manufacturing facilities. We also continually strive to meet and exceed the standards recommended by the Occupational Safety and Health Administration.  Our company also meets the guidelines set out by the National Fire Protection Association with our highly efficient dust collection systems and replacement cartridge filters.

If you’re asking yourself if a spark trap is really necessary– the answer is yes! Consider the findings of the OSHA’s National Emphasis Program.  It shows that metal dust accounts for 20% of explosions nationwide. Also, 7% of ignition sources are ignited by fabricated metals while another 8% of ignition sources are caused by Primary metals. If you want to reduce the possibility of an accident at your metalworking facility, you MUST invest in spark arrestors!

How Can  Spark Trap Safety Systems Reduce Explosions?

Adding a spark trap to your industrial dust collection system is like adding a security system to your home. You already have the proper amount of protection with locks, but installing a security system in your home provides another line of defense, keeping you and your family safe.

Our spark trap, named Spark Arrestor, is the first line of defense in protecting your metal fabricators and your metalworking facility from explosions.  Spark Arrestors extinguish nearly every spark before it enters into the main containment unit where combustible dust and other flammable material collects. When you choose our Spark Arrestors, you’ll receive a quality product made with heavy duty materials that is highly effective at keeping sparks from entering your industrial dust collector.

Here are some key features you’ll receive when you invest in our spark traps:

  • Maintenance free components
  • Fully welded construction
  • Easy install for any system
  • No moving parts
  • Available in carbon steel or stainless steel

Dust Explosion Dangers Case Studies

WHEN WATER TURNS A FIRE INTO AN EXPLOSION

 

A combustible dust explosion is an ever present danger for workers in many industries. These two examples show that despite increased awareness, explosive dust still puts lives at risk. One thing they both have in common: water may have actually made them much worse.

dust explosion

The first example shows how even things that seem like safe and practical fire-fighting measures can lead to disaster. In May, a grain dust explosion in a silo injured a worker who was attempting to put out a dust fire with water.

 

Because the very fine dust was contained in the silo, all the criteria for an explosion were present… except for one. The dust provided fuel for a fire, and the open silo hatch provided oxygen. With the material confined in the closed space of the silo and an ignition source in the form of a grain dryer, an explosion was waiting to happen.

 

Ironically, it was the worker spraying water onto the fire that created the explosion by adding the last element: dispersal of the dust. Water hitting the dust added more air and also raised a cloud of dust. Dust suspended in the air turns the situation from a fire into an explosion. In this case it blew the roof off the silo and caused serious injuries.

Fish Meal Dust?

The second example is in some ways a classic industrial dust explosion, except that the material isn’t one you’d expect. In September, a seafood processing plant was seriously damaged and had to be shut down because of an explosion caused by the ignition of fish meal dust.

 

Fish meal is a fine, dry powder that’s often made into fish food. A local official noted that this is the third time he knows of that fish meal has caused an explosion at a local plant. In this case, a burst pipe may have created an explosion by causing dust to become airborne.

 

While people don’t think of fish as being explosive, they usually don’t think of metal as being explosive either. Both of them are only dangerous when they’re turned into a dust.

 

While we talk a lot about combustible metal dust and fumes because many of the industries we work with use metals, organic dusts like grain, spices, powdered milk and egg, sugar, tobacco, and yes, even fish are dangerously explosive if all the right elements are present.

 

While many places that produce metal dust are aware of the risks, some places that produce organic dust don’t realize how dangerous it can be, or how important a dust collection system is for controlling and handling dust. The most catastrophic damage is often done by secondary explosions: a small dust explosion causes accumulated dust to be dispersed in the air, causing a much larger explosion. Spraying water on a dust fire can do the same thing, sending dust into the air.

 

Removing dust from the facility and collecting it with a dust collection system designed to prevent or safely control explosions is an important safety strategy. Making sure there is no dust dispersed in the air is another key to explosion prevention. In any situation with combustible dust, the system needs to be equipped with safety features such as spark arrestors, explosion venting, and chemical suppressors.

Workplace Hazard Exposure A Crime?

Yes, workplace hazard exposure is a serious offense.  As of this year, the Department of Justice and the Department of Labor (which includes OSHA) are partnering to bring federal charges against companies who expose workers to hazardous materials and carcinogens.

workplace hazard exposure

 

This partnership is intended to let prosecutors use powerful environmental protection laws to prosecute companies for worker safety violations involving exposure to dangerous substances. This will allow prosecutors working on OSHA worker exposure cases to work with the Environmental Crimes Section of the Department of Justice to maximize penalties and criminal charges.

 

In many cases, environmental protection laws are stricter and have stronger punishments than OSHA regulations. Environmental protection has wide public support and considerably more funding than occupational health and safety. There is an entire division of the Department of Justice that handles environmental crimes, and these may carry a much heavier fine or more serious criminal charges.

 

OSHA’s ability to level criminal charges is usually limited to situations where an employer willfully and knowingly violated safety standards and caused the death of a worker. These cases can be difficult to prove and even more difficult to prosecute. Under the laws regulating environmental crimes, releasing or failing to control any workplace hazard exposure to dangerous substances can be considered a crime, even if the exposure does not result in death or serious injury.

 

Just like with OSHA fines, the most serious criminal charges will go to employers who repeatedly violate the rules or who fail to correct problems even when they know about them. Bringing in the Department of Justice and their regulation of environmental laws is likely to affect companies who aren’t following the rules for controlling or cleaning up their hazardous materials.

 

Workplace hazard exposure includes materials such as dust and fumes from many types of industrial processes.  Some examples are welding, plasma or laser cutting, manufacturing of plastics and resins, printing inks and pigments, as well as production of chemicals or fertilizers.

 

OSHA usually sets exposure limits for employees. Environmental regulations set limits for how much of a material can be released into the environment, regardless of the exposure to individual employees. Under the Department of Justice, hazardous materials being released inside a facility can be handled under environmental laws.

 

For metalworking facilities, hexavalent chromium, manganese, and other components of cutting and welding fumes are heavily regulated as environmental toxins. Exposing people to these materials, inside or outside, can be an environmental crime. Hexavalent chromium often contaminates drinking water, and it’s a major environmental concern.

 

For any company that either uses or produces hazardous dust or fumes, a dust collection system is very important for limiting exposure. The system will not only keep the materials away from workers, but also collects them safely and allows you to dispose of them properly. A dust and fume collection system that’s maintained and used correctly is a necessary tool for controlling hazardous airborne particles or fumes.

PHOSGENE GAS AND WELDING: IS IT BAD?

Phosgene became infamous when it was used as chemical warfare in World War I. In numerous welding forums and opinion pieces, people share concerns about phosgene gas produced while welding.

Is this a fact or a myth?

phosgene gas

Phosgene is used in some industrial processes. It can also occur as a breakdown product from chemicals called chlorinated hydrocarbon solvents. These have names like trichloroethylene and methylene chloride.

 

These are very common chemicals. Pesticides, degreasing chemicals, and solvents are all examples. Older refrigerators also still contain coolants that can convert to phosgene when heated. According to the available information, phosgene is produced as a component of welding fumes when metal that’s been cleaned with a solvent or degreaser (brake cleaner is the usual culprit).

 

In one example, a man using repairing a refrigerator was exposed to phosgene as a result of heating the coolant with a welding torch. He suffered extreme shortness of breath and irritation to his throat and lungs. He was admitted to intensive care and recovered. There are many other stories of people reporting that they or someone they know was exposed to and injured by phosgene welding fumes.

 

So what are the facts?

 

Some brake cleaners, degreasers, and solvents do contain chlorinated hydrocarbons. These products carry a warning label about toxic gases and fumes, and some of them specifically mention phosgene. Warning labels, while not exciting reading, should always be followed. So it’s absolutely possible to poison yourself with phosgene if using these chemicals incorrectly.

 

Is it a real danger for welders?

 

There doesn’t seem to be much solid information about that. The example of the man who was injured while using a welding torch to work on an old refrigerator is true (Journal of Accident and Emergency Medicine, 12 pp212-213 (1995)). Many people report that they or someone else suffered an exposure to phosgene while welding something that had been cleaned with brake cleaner. There doesn’t seem to be a lot of reliable information about this problem, though. It’s definitely something that could happen, but there’s not much information about how often it actually does happen.

 

Do you know someone this has happened to, or has it happened to you? Have you ever experienced dangerous fumes while welding? Do you have any information about welding, phosgene gas, and brake cleaner that people should know about?

Energy Cost Savings Through Your Dust Collector

HOW YOUR DUST COLLECTOR CAN PAY FOR ITSELF

Installing a dust collection system (or updating an old one) is a big investment. Safety, health, and compliance are all important reasons to do so.  Will energy cost savings with this investment benefit your company in the long run? When a company is looking at spending that kind of money, it helps to be able to talk about a more immediate return on your investment.

 

The good news is that your new system can pay for itself in as little as two years by saving you a lot of money on heating and cooling costs.

energy cost

It’s hard to put a dollar amount on employee health, but it’s easy to put a dollar amount on how much you spend heating and cooling your building. If you’re spending that money and then venting heated air outside the building, you’re effectively blowing money out the window.

 

Many of our CMAXX systems have paid for themselves within two years just in energy cost savings. And they will continue to save their owners money for many years of service. Some companies have even been able to find energy conservation incentives that save them money on the immediate cost of a system.

 

Recirculating air back into the facility can be an excellent cost-saving measure, but only if it doesn’t compromise the health of people working there. This means that the recirculated air has to be completely clean and safe.

 

If you’re planning to recirculate air, it’s important to make sure that your system is equipped to handle the type of dust you’re producing. Particles from welding fumes and laser or plasma cutting smoke can be as small as half a micron. This usually requires a filter with a rating of at least MERV 15, meaning it is more than 95% effective for particles down to 0.3 microns. If there might be dangerous or highly regulated materials (such as hexavalent chromium) in the dust, a HEPA filter may be necessary for air that’s going to be returned inside.

 

Besides the savings on energy costs, a system that recirculates air can actually be more efficient. In some ambient systems, the clean air enters at the level where people are working, which moves the dirty air out of the work area and toward the collector. These types of systems are very effective at filtering the air in larger spaces.

 

If a dust and fume collector is something you’re going to need anyway, the tremendous savings in  your energy cost might be what it takes to get that project into the budget. After all, those heating and cooling cost savings will go back into the budget year after year, and that’s something everyone likes to hear.
