Tech Forum: What’s Your Confined Space Rescue Plan?

0

Jimmy PeckCleaning, repairing or inspecting critical equipment often requires workers to enter small spaces like tanks or pipes where they may be exposed to hazardous material. Commonly referred to as “confined spaces,” these areas are characterized by their tight configurations that may hinder the activities of any employee who must enter, work in and exit them.

To protect employees from harm, OSHA has developed a set of requirements that govern the way employers manage confined space projects. Provisions of these standards range from posting visible danger notices, to evaluating the workplace on a consistent basis and documenting any issues. However, perhaps most important is the provision that requires employers to develop and implement procedures for mobilizing rescue or emergency services in the event of a crisis.

Selecting your Emergency Response Team

In July 2017, three Florida underground utility workers died after losing consciousness in a 15-ft deep drainage hole due to a buildup of hydrogen sulfide and methane. According to reports of the accident from EHS Today, the second worker entered with the intention of saving the first trapped individual but also lost consciousness. Likewise, a third man climbed into the hole and was overcome by gas. All three workers lost their lives – none of them were wearing proper respiratory protective gear or gas monitoring equipment.

These incidents happen all too often in industrial environments, but what’s more upsetting is that accidents such as the one in Florida are entirely preventable.

OSHA defines a confined space as any environment that meets all of the following criteria:

  • Is large enough for a worker to enter;
  • Has limited means of entry or exit; and
  • Is not designed for continuous occupancy.

Further, OSHA uses the term “permit-required confined space” (or permit space) to describe those spaces which both meet the definition of “confined space” and pose health or safety hazards. The Final Rule for Permit-Required Confined Spaces took effect in 1993, after years of gathering data on confined space fatalities.

Historically, when selecting a response team to support confined space efforts, many organizations partner with their local fire department and emergency crews to devise an action plan. While this solution is perfectly adequate in the eyes of OSHA, companies are often encouraged to have a group of trained professionals on site who are ready to react immediately.

Regardless of the selected team, OSHA offers several tips for evaluating an emergency service to ensure they are capable, available and prepared. Some questions to consider include:

  • Do you have the necessary equipment for the particular permit-required confined spaces?
  • Have you been trained to handle the hazardous conditions associated with this specific confined space? (i.e., hazardous gasses or liquids)
  • Are you able to respond and conduct a rescue in a timely manner? Can you visit the site to practice rescue techniques with our team?

MPW’s Confined Space Rescue Team

MPW recently worked on a customer site in which two separate rescue scenarios were identified. The confined space in question was a tank, roughly 25 ft tall and 15 ft in diameter. The tank was split vertically in two sections, an upper and lower section, caused by a screen floor in the tank.

To complete the work requested by the customer, MPW’s Industrial Cleaning team was required to enter the upper section, followed by the lower section to complete the job. As part of MPW’s safety training, personnel, during entry were required to wear an air-purifying respirator due to atmosphere hazards, in addition to their normal personal protective equipment.

Due to the dangerous application requirements, MPW’s Confined Space Rescue team was also retained to support the project, as part of the established confined space rescue plan. During the project, MPW’s team was staged right outside the barricade beside the confined space during operating hours. This reduced an already short response time and the people on the rescue team knew the crew and how they worked.

Thankfully, there were no injuries or incidents reported on this specific project, but the confined space rescue team was present and ready for the duration of the job – putting MPW’s workers at ease and significantly reducing potential liabilities for the customer.

Promoting a Safety First Workplace

No company wants to believe the unthinkable will happen – it’s human nature. But as with any dangerous situation, adequate preparation will help keep workers safe in the event of a crisis. Evaluating partner response time, improving communications among co-workers and selecting a partner that is knowledgeable of the work site and its potential hazards are the keys to mitigating risk during a confined space project.
