Safety in Confined Spaces

Confined Space Safety: What is it?

Confined space safety is the practice of ensuring secure working conditions in fully or partially enclosed places, such as manholes, pipes, boilers, utility vaults, and storage bins. Appropriate confined space safety practices should be followed in order to adhere to health and safety regulations and prevent work-related accidents, illnesses, or even deaths.

Confined Space NIOSH

According to the National Institute for Occupational Safety and Health (NIOSH), a confined area is one that is not intended for continuous worker occupancy, has few openings for entry and departure, poor natural ventilation, and the potential to contain or generate toxic air pollutants.

While NIOSH offers evidence-based advice to prevent work-related injuries, OSHA enforces legislation. It follows that NIOSH’s use of the term “unfavorable natural ventilation” in their definition of a confined space is empirical.

HSE in Confined Space

An area that is substantially enclosed (though not always completely), and where there is a risk of serious injury from things that are present there or nearby, is what the Health and Safety Executive (HSE), which regulates occupational health and safety laws in the United Kingdom, defines as a confined space (e.g. lack of oxygen).

The HSE emphasizes that confined space safety also applies to any substances or conditions outside the enclosure, even though OSHA and NIOSH are clear that confined areas are not intended or built for continuous worker occupation.

In a Confined Space, WorkSafeBC

WorkSafeBC, a governmental organization with its headquarters in British Columbia, Canada, only defines a confined place as an enclosed or partially enclosed space large enough for a worker to enter.

However, they included examples of limited areas that had all four sides, like a tank, or only two sides, like an enclosed conveyor. According to WorkSafeBC, confined spaces are not meant for normal work.

Permit-Required Confined Space: What Is It?

A confined place that requires a permit, commonly called a “permit space,” contains or has the potential to contain a dangerous atmosphere or any other major health and safety risks.Permit-required confined locations are regarded as high-risk workplaces and are governed by strict access and safety requirements.

What Does a Confined Space Safety Rescue Plan Entail?

A series of actions conducted by designated personnel to rescue workers from permitted spaces is known as a restricted space rescue plan. The equipment used for non-entry rescue of people from permit places, as well as other equipment required for safe entrance into and rescue from permit locations, is frequently employed by the rescue and emergency services. The following are the OSHA standards for a confined space rescue plan:

Create and implement protocols for calling in rescue and emergency services, rescuing people from permit spaces, giving rescued workers the appropriate emergency care, and keeping unauthorized personnel from trying to perform a rescue.

Examine a potential rescuer’s readiness to act quickly in response to a call for help while taking the hazards into account.

Determine whether a potential rescue service has the skills and equipment necessary to operate effectively while rescuing participants from the specific permit space or types of permit places mentioned.

Pick a rescue crew or service from those that have been examined.

When a rescue team or agency is dispatched to the scene, make sure they are all aware of the potential dangers they may face.

All designated permit places should be made available to the chosen rescue team or agency so that they can practise all potential rescue scenarios and prepare the necessary plans.

Provide the personal safety equipment (PPE) required for permit space rescues, as well as the training necessary for affected personnel to be effective in using that PPE, at no expense to those employees..

Prepare impacted workers to carry out designated rescue tasks.

Develop basic first aid and CPR skills among the impacted staff (CPR).

At least once every year, make sure that affected staff practise doing permit space rescues.

Every time a legitimate entrant enters a permit space, retrieval mechanisms or methods must be employed to facilitate non-entry rescue, unless doing so would raise the risk of entrance overall or would not aid in the entrant’s rescue.

Why Is It Important to Work Safely in a Confined Space?

Statistics show that 90 people in the US alone die on average every year while working in restricted zones. Because of the presence of lethal gasses while performing particular occupations, the majority of these accidents result in asphyxiation or oxygen deficit.

To guarantee that all participants will have proper protection while doing their duties inside the limited space, detailed safety procedures must be carried out thoroughly. Employers are also responsible for educating their employees about safety rules and enforcing them. For additional information checkout confined space refresher course

Safety Risks

Working in a confined space presents many risks, but the most dangerous one is the deadly atmosphere caused by the presence of carbon monoxide, hydrogen sulphide, and methane gas, which can cause an oxygen shortage or asphyxiation. Other typical confined space concerns include unsecured equipment, live wires that are exposed, and heat exhaustion.

How much oxygen is there in enclosed spaces?

21 percent oxygen is required outside the confined environment to maintain life.Oxygen levels are prone to drop in compact spaces.. It could be utilized for slime, rust, and bacterial growth. Another gas may enter the confined space and replace the oxygen. The use of heat will deplete oxygen.

If oxygen is reduced to between 12 and 16 percent, workers will experience loss of coordination and an increase in their heart rate and breathing. If the oxygen level drops to 6 to 10 percent, they will experience nausea, vomiting, loss of consciousness, and possibly even death.

Risk evaluation using Auditor

Deep understanding of safety regulations and procedures is necessary when working in confined spaces to protect all entrants from recognised hazards. A mobile app and cloud-based solution called iAuditor by SafetyCulture enables teams to gather reliable data to confirm that all participants received proper protection while carrying out their duties in restricted spaces.

Safety officials may conduct confined space risk assessments on mobile devices whenever they want, anywhere they are, even offline, thanks to iAuditor. For more accurate reports, they can quickly take, annotate, and attach images of non-compliant goods. With just one touch of the finger, confined space risk assessments can be instantly emailed to any employee of the company following the inspection.

Training in restricted areas can protect your personnel from operational risks in the workplace.

Because manual labor by its very nature carries risks, working in the construction or mining industries is unavoidable. Naturally, workers must have the necessary training before being deployed when operating in enclosed locations with few entry or exit ports and restricted access. This covers the safety precautions that employees should take throughout their shifts as well as the protective gear they should wear on the job site. In the event of an accident, such as the blocking of entry or exit access or the collapse of any locations where they are working, it is crucial to also provide them with an exit strategy.

In order for the employees to know what to expect while working on-site, it is always best to train them on what they may do when confronted with risky scenarios. Additionally, it will assist your personnel in developing the knowledge and abilities necessary to effectively reduce the risks associated with working in confined areas.
