Working inside a confined space is completely different from working in a non-confined space.
The difference especially comes from its potential hazards.
As you already knew that there are a lot of hazards associated with confined space work.
And most of them are the deadliest hazards.
Because of this reason, confined space work requires a more complete set of safety equipment to ensure workers’ safety.
In this post, we will discuss in detail the confined space entry equipment list, one by one, to help you identify all of them.
The list is made based on OSHA confined space equipment requirements.
Confined Space Entry Equipment List
Here is the confined space entry equipment list that you can use as a guide.
Testing and monitoring equipment
Gas measurement or testing inside a confined space is a must. Toxic gas such as hydrogen sulfide (H2S) and carbon monoxide (CO) are the first gases that needs to be measured.
The second gas is explosive or flammable gas (LEL or lower explosion limit).
And the third is oxygen.
The portable gas detector is a multi-functional detector, which can analyze all gases mentioned above in one time analysis.
Besides that, this portable gas detector is very useful in monitoring those gases during the confined space work in progress.
It is also to notify others that workers are doing jobs inside a confined space.
This is very important in order to avoid miss operation by unintended people who may operate the valve of the machine that will endanger workers inside it.
Clear communication between workers in confined spaces and workers outside of it is very important.
A product like Arcshell Rechargeable Long Range Two-Way Radios is a good choice for this purpose. This product has an earpiece for ease of use.
Confined Space Trained Sticker
The use of this sticker is to notify others that a worker who uses it on her or his safety helmet, is a qualified worker who is allowable to work inside a confined space.
Personal protective equipment (PPE)
Full Body Safety Harness
Falling from height is one of the confined space hazards. So, fall protection PPE – full body safety harness – is necessary.
It is not recommended to use a safety belt for fall protection due to it contains a new potential hazard.
Chemical splashes, small objects, and particles may injure workers’ eyes. Provide safety goggles with adequate specifications for workers who work in a confined space.
This is the mandatory PPE that workers must wear at almost workplace types including confined space.
When cleaning up a chemical storage tank, this PPE must be available to protect workers from chemical exposure.
Besides the above PPE, other PPE that is necessary for confined spaces include ear plugs, face shields, welding shields, safety helmets, etc. This will depend on the nature of the confined space.
Lighting equipment approved for ignitable or combustible conditions
Generally, a confined space has a low light intensity. Additional lighting is necessary to provide enough light for safe working inside it.
However, general lighting equipment specification is not enough when the confined space contains combustible or flammable liquids or gases.
An explosion-proof lighting equipment must be provided.
A product like 16W LED CNC Machine Light Interner Lighting is suitable for ignitable or combustion conditions. It meets IP67 specifications.
Besides lighting, an explosion-proof socket is also necessary.
Barriers and shields to protect the space
To prevent unintended entry, safety barriers, and shields must be available surrounding the confined space.
It is also to notify others about confined space work is in progress.
Confined space barricade tape, mobile barricade fence systems, retractable safety cones, and fixed wall mount retractable safety belts are some of the barrier and shield examples that you can choose for this purpose.
Other equipment is plastic manhole shields.
Rescue and emergency equipment
A Tripod is a portable three-legged frame, used for connecting a winch for supporting worker weight, supplying working tools, and attaching rescue equipment.
Safe-locking device for declining and rising workers, working tools, and materials. It must be safe and reliable.
It is for connecting the user’s safety harness with a hook at the falling protector, fully ensuring the user’s safety and preventing falling during rescue and construction.
In case of emergency, when there is no other way to get the victim from a confined space, retrieval wristlets are a good choice.
Semi Static Ropes
Semi-static ropes are required for rescuing from a confined space. Select only high-quality semi-static ropes, like the products from Xmonster.
Any other equipment needed for safe entry, exit, or rescue from permitted spaces
Removing remaining flammable, toxic, and inert gases from a confined space shall be done completely before entry.
An exhaust blower can do such a job quickly. Just make sure that you choose the right capacity before ordering.
An example of an exhaust blower for confined space work is Allegro Industries 953325 Plastic Compaxial Blower AC with 25′ Ducting and Canister Assembly, 8″.
Other equipments necessary for safe entry are manhole ventilation pass-through and manhole lid lifter.
