Enter By Permit Only: 13 Confined Space Hazards That Can Kill

Posted by Joshua Fleishman on Mon, Dec 29, 2014 @ 01:00 PM

A "confined space" as defined by OSHA, is a space that is large enough so that an employee can bodily enter and perform assigned work, has limited or restricted means for entry or exit, and is not designed for continuous employee occupancy. Examples include (but are not limited to) boilers, tanks, vessels, stills, silos, mixers, storage bins, hoppers, vaults, vats, and pits.

Permit required confined space entryA permit required confined space is a confined space that requires a special permit to enter. These usually contain (or have the potential to contain) a hazardous atmosphere, an engulfment or entrapment hazard, or physical hazards. If any other serious safety or health hazard are present, it may also be classified as permit-required. Some companies even take a step further than the OSHA requirements and choose to treat every confined space onsite as a permit required confined space and follow all processes and procedures pertaining to those types of entries. 

Confined spaces are considered one of the deadliest places in the workplace because of the potential for danger. Many different types of hazards are found in confined spaces. Atmospheric issues can arise, which aren't always apparent. Oxygen is a basic necessity for life, but if there is too much or too little in a confined space, atmospheres can become deadly. Flammable or toxic gases/vapors are sometimes invisible to smell or see, and without proper equipment you would not be able to tell otherwise. Residue of previous chemicals can be left behind, the configuration of the space, the nature of the work, external hazards, and even outside hazards (animals, insects, noise, etc.) are examples of potential dangers surrounding confined spaces and why they are considered dangerous. Confined spaces are also prone to changes in the level of safety at any given time. Perfectly normal, common work conditions can quickly turn into an IDLH (Immediately Dangerous to Life or Health) atmosphere with some help from the hazards listed.

Confined Space Hazard Types

  • Oxygen Rich

    • Example: Oxygen is greater than 23.5%

  • Oxygen Deficient

    • Example: Oxygen is lesser than 19.5%

  • Flammable Vapors/Gases

    • Examples: Possible chemical reactions, combustible dust

  • Toxic Atmospheres

    • Examples: Carbon monoxide, hydrogen sulfide

  • Corrosive Atmospheres

    • Examples: Hydrochloric acid, ammonia

  • Physical Hazards

    • Examples: Ladders, scaffolding, wet surface, poor lighting

  • Mechanical Hazards

    • Examples: Mixing vessels, falling objects

  • Surface Hazards

    • Examples: Slips and falls

  • Noise Hazards

    • Example: Grinding work and loud environments may interfere with communication and delay rescue or emergency services if needed

  • Vibration Hazards

    • Example: Woodworking tools

  • Engulfment Hazards

    • Example: Entrapped by contents of a confined space

  • Temperature Hazards

    • Examples: Heat stroke or heat stress, burns from hot surfaces, and freezing from extremely cold surfaces

  • Electrical Hazards

    • Example: Hazards from equipment taken into the space

ALWAYS REMEMBER TO LOCK AND TAG OUT EVERYTHING THAT COULD MOVE AND INJURE WORKERS!


Confined Space Rescue

Where a system of entry permits is in place, a rescue plan is required. It will list the personnel and equipment required to be at the worksite before entry is allowed. Special equipment such as tripod hoists, harnesses, and others may be required to extricate a worker from a toxic environment, without unduly endangering rescue personnel.

Farm Safety in the USA [Infographic]

Posted by Joshua Fleishman on Tue, Dec 16, 2014 @ 09:30 AM

Safety is a top priority in any industry, and the farming and agriculture industry is no different. Today, we will take a look at how hazardous the industry is and how at risk farmers are for fatal and nonfatal injuries.

Agriculture is one of the most hazardous industries people can work in. Almost 2 million people are directly employed in the agriculture industry so it is certainly an issue that needs to be addressed. Every week there are people injured and even killed in the USA on farms and in agriculture related industries. One stark statistic is that every day approximately 167 agri-workers suffer a lost-work-time injury. Through implementation of safer work practices and measures however, these numbers could be greatly reduced. Education and training is a major element that can assist this.

This infographic (Credit: farmerjournal.ie) covers the area of farm safety and agriculture in the USA and examines some interesting and startling statistics associated with it. It also gives some recommendations on how some of these accidents and fatalities can be avoided in the future.farm safety, safety training
