Confined spaces are far from the cleanest places around. Sometimes they are soggy as well. If your work requires you to be be in a space where the water cannot be turned off - a storm drain or other water system for instance - a dewatering or sludge pump may be the answer. Confined spaces require small pumps that are portable and can move major amounts of water. Allegro Industries makes top quality pumps specifically for clearing work spaces and they can continue running for long per …

For electricians and electric power industry workers the threat of electrical arc is the most serious they face. During their short blasts, flash hazard temperatures can be literally hotter than the sun. Combine this with the pressure wave from the explosion and searing flying metallic particles, and you've got yourself a seriously bad situation. The clothing electrical workers choose can play an important role in how serious an injury is received in the event of one of these arc blasts. …

Confined space entry requires a method of extraction for the entrant if they become incapacitated. Often this requirement is met by erecting a tripod over the entry point. At Pksafety.com we offer two types of tripods, and people generally choose one or the other depending on how often they will be using them. The less expensive model is the AK105A 8 ft. tripod. It's great for occasional use, and is lightweight and easy to assemble. One drawback is that the Protecta AK …

Some confined spaces just aren't fit to breath in. Respiratory protection, whether for work in a space with Immediate Danger to Life and Health (IDLH) or in a rescue operation where air filtering or purifying respirators are not an option, has two critical requirements: First, it must provide a clean air supply. Secondly, it cannot interfere with safe entry and exit from the space. The two types of breathing devices that fit these requirements are a self-contained breathing apparatus (SCBA …

Just as heat in confined spaces can cause added danger to entrants, so too can cold temperatures. Here are a list of procedures to follow to avoid cold-related injury while working in a confined space: Increase the temperature by heating the atmosphere within your confined space. If you decide to heat the environment, be sure it is safe to do so. You don't want to introduce a new ignition source to the area. Also when heating a confined space, you must ensure there is no increase in vap …

Protecting your hands is critical when performing confined space work. But what is the best way to keep them from harm? Is there a possibility of contamination or chemical exposure as well as sharp edges? Do your safety gloves allow you to perform rope access work? Unfortunately, there is no one type of glove that covers every situation. You will need to understand what hazards your confined space offers before you can know how best to protect your hands. We've put together a few gui …

Hydration is often a forgotten element of safety in a confined space. With so many potential hazards during confined space entry, loss of water because of sweating isn't high on the list for many workers. However, hydration is just as important as many of the other safety considerations of a confined space project. Fluids lost in a hot environment, or because entrants are wearing protective, and non-breathable clothing, must be replaced to help prevent heat-related injuries. To pr …

Working at height can be dangerous. Welding is also rife with hazardous possibilities. Do them both at the same time and you're a special type of person. This photo was taken during a highway traffic stop in Costa Rica. While I don't consider the typical Costa Rican construction project to be overly safe, I was amazed to see the level of safety exhibited in this photo. First let's look at the highway workers. They're all wearing reflective safety vests. They are also wearing hard hat …

Typically gases such as nitrogen or carbon dioxide are used to remove oxygen from a confined space and render it inert. Often an area is made inert in order to remove the potential for fire, or to stop oxidation of a product within a space and keep it from spoiling.  If you are attempting a rescue, or have other need of entry, you must be able to anticipate what changes may result within the space if you return an oxygenated, breathable atmosphere to the area. To do this, you must …

For an oxygen-rich atmosphere, it's important to always make sure that gases expelled from the confined space through ventilation do not come into contact with internal combustion engines, flames or other sources of ignition that may cause an explosion or accelerate burning. While this might seem obvious, it is sometimes overlooked in the rush to clear a confined space and make it safe for entry. When sizing up a potential confined space for entry, also be aware of where you are p …
