About OSHA 29 CFR 1910.242(b) for Compressed Air Safety

In February of 1972 OSHA released a standard to improve worker safety when operating handheld compressed air devices being used for cleaning purposes. This directive focuses around human skins permeability. That is, if you were to take an open ended pipe that had compressed air being discharged over 30 psig it can actually push through the skin and create an air embolism.

OSHA’s Directive 29 CFR 1910.242(b)

Air Embolisms are extremely painful, and in extreme cases, can be deadly. The risk associated with an air embolism can be mitigated by following the OSHA directive and reducing the downstream pressure of an air nozzle or nozzle pressure below 30 psi for all static conditions. Dead ending is when the passageway for the air becomes blocked and turns a dynamic flow of air into a static flow. This is in the event the pipe, nozzle, lance, etc. becomes blocked by a human’s body. This is a directive that all Intelligent Compressed Air® products from EXAIR focus on meeting or exceeding.

Our Air Nozzles and Jets video shows a great depiction of how this can be achieved with our engineered design of nozzles. The recessed holes and the fact that there are multiple passages for the air to exit are easy to see on the nozzle. Products like the Super Air Knife may not be so easy to see but the way the air knife cap overlaps prevents the Super Air Knife from being dead ended in the event an operator comes into contact with the discharge air.

Even though this directive was created in 1972 it continues to be at the forefront of industrial environments. I have even been to a custom artwork facility that was effected by this standard because they would use a handheld blowgun to remove dust and debris before matting and framing artwork with glass. They also removed dirt and dust from the frames before paint. This wasn’t your typical manufacturing environment yet they were still held to the same standards and were made safe by implementing engineered solutions such as our Super Air Nozzle.

This promotional item, the model 1126 1″ Flat Super Air Nozzle, has a patented shim to blow a 1” wide stream of air to clean surfaces quickly and efficiently and is a $45.00 USD value. For more details on the Promotion, click on the photo/link above. For more information about the Flat Super Air Nozzles, click HERE.

Inexpensive air guns can be purchased just about anywhere- online, via catalogs, and through industrial supply companies. Typical quality is less than ideal – broken triggers, leaky valves – a short lifespan in an industrial setting are merely a few of the issues observed.  Most are loud and inefficient – they just blow large amounts of compressed air, and at noise levels that violate OSHA requirements.  Some may even generate dangerous dead end pressure situations that that can result in serious or fatal injuries if blocked.

EXAIR’s Safety Air Guns have been engineered and designed to eliminate these issues. They are durable for use in industrial situations and comfortable to use for extended periods of time.  With an EXAIR engineered air nozzle, each model provides top performance by entraining large volumes of surrounding air into the air-stream. Operation is assured to be safe along with low compressed air consumption and noise levels.  Due to the design, the airflow that exits the nozzle cannot be blocked, as required by OSHA Standard 29 CPR 1910.242(b).

Increase Safety and Gain OSHA Compliance By Using An Engineered Solution

In 1972, the US Department of Labor’s Occupation Safety & Health Administration (OSHA) established Standard 29 CFR 1910.242(b) to reduce the outlet pressure to less than 30 psi, of an open pipe, nozzle, air gun, etc. when being used for cleaning. The intent of this directive was to prevent injury to operators. They determined that 30 psi was the pressure in which the skin could be broken if the device were dead-ended against the operator’s body, causing an injury known as an air embolism…the dead-ended force of the air, under pressure, breaks the skin and introduces air flow inside the body. This is a VERY dangerous condition which can quickly lead to serious injury, possible stroke or ultimately death.

While OSHA doesn’t recommend any type or manufacturer of device, they do provide two methods you can follow to gain compliance.

The first would be to reduce the operating pressure below 30 PSI, as shown in the below line drawing.  This, of course, limits the strength and usefulness of the exhausting air flow before it reaches the nozzle and before it is used upon the application.

 

The other method indicates using a nozzle which includes a pressure reducer or a relief device which will reduce the air pressure to less than 30 psi if the nozzle is dead ended. All of EXAIR‘s products are engineered to meet or exceed this Standard. In the case of our Super Air Nozzles, the air exits through a series of jets, recessed behind an array of fins, so the outlet holes cannot be blocked directly, any potential obstruction of the outlet air holes results in the air having an alternative route to avoid injury to operators and personnel. This allows the full pressure (the highest energy) to reach the nozzle and the application

Open air lines and homemade blow offs violate OSHA standard 1910.242(b) because of harmful dead end pressures. If you would like to discuss how EXAIR products can help you gain OSHA compliance to increase personnel safety and avoid costly fines, please give me a call, I’d be happy to help.

EXAIR Leads the Way with Product Standards

Standards seem to continually get introduced and updated. There is an ever increasing number of local, regional, federal, and even global standards to comply with.  We pay close attention to these standards and have the largest number of standards upon our products.

meets or exceeds oshaThe standards the every EXAIR product meets or exceeds are the OSHA standards for dead-end pressure as well as allowable noise level exposure.  The dead-end pressure directive is OSHA standard 29 CFR 1910.242 (b).  The standard refers to the fact that compressed air can be dangerous when the outlet pressure of a hole, hose or copper tube is higher than 30 psig (2 BAR).  In the event the opening is blocked by a hand or other body part, air may enter the bloodstream through the skin, resulting in a serious injury.  All of the compressed air products manufactured by EXAIR have been designed for safety.  All are safe to be supplied with higher pressure than 30 psig and still meet or exceed the OSHA standard.

The OSHA standard 29 CFR – 191.95 (a) refers to the maximum allowable noise exposure that an operator is permitted to be exposed to for a given period of time.   The chart of allowable exposure times is shown below.   All EXAIR products are engineered to create the minimum amount of noise while efficiently utilizing compressed air.   Many times blow offs are cross drilled to permit air to escape in order to meet the OSHA standard for dead end pressure, this process increases the noise level generated by that blow off considerably.

OSHA Noise Level

One of the most stringent compliance that EXAIR has upon its products is the UL/CUL listings and recognition.  All EXAIR Cabinet Cooler Systems are UL listed, we were the first to insure your electrical cabinet’s NEMA integrity remained by putting our Cabinet Cooler systems to the UL test. This means that the Underwriters Laboratories have deemed these products safe for operation throughout the US and Canada per their standards that are applicable for each of the product groups.   The products undergo numerous tests and scenarios to ensure that an operator will be safe during the normal operation of the units.   The tests for the Cabinet Cooler Systems includes environmental exposure for the given NEMA type of the enclosure along with many other tests.  The Static Eliminator Power Supplies are also UL listed.

cULlistedcULrecognized

CE is another standard which EXAIR pays great attention to to meet or exceed. CE is a standard that is normally preferred when dealing with countries outside of the US but is gaining popularity within the states as well.  CE being a European standard actually stands for a french phrase, “Confrmité Eurpéene” which is translated to “European Conformity”.  Any EXAIR product displaying the CE mark conforms where there are applicable directives.CE

The RoHS directive is targeted on heavy metals that are generally found within electronics.  Substances like Mercury, Lead, Polybrominated biphenyls, Cadmium, or Hexavalent chromium.  In order to meet the RoHs directive a product must have 100 parts per million or less of mercury and for other substances there must be less than 0.01% of the substance by weight in a raw homogeneous materials level. All EXAIR products which are electronic or contain electronic devices are compliant to the 2002/95/EC RoHS directive, also including the amendment outlined in the European Commission decision L 214/65.  This includes all EXAIR Static Eliminators, Electronic Flow Control, and Electronic Temperature Control products.ROHS_Vector

EXAIR maintains records to be sure our supply chain is providing product which meets the conflict mineral free guidelines of the Dodd-Frank Act.  EXAIR supports Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and we are committed to compliance with the conflict minerals rule in order to curb the illicit trade of tin, tantalum, tungsten and gold in the DRC region. EXAIR is using the CMRT 3.02 template to document our supply chain and commitment to conflict free products. When requested we will even provide the needed forms to support our customer’s efforts in complying with the Dodd-Frank Act.

conflictfree

REACH, is another European Community Regulation this time on chemicals and their safe use.  REACH is targeted to ensure personnel and environmental health by identifying the intrinsic properties of chemical substances easily.  REACH stands for Registration, Evaluation, Authorization and Restriction of Chemical substances and was written into law in 2007. EXAIR products are not required to be registered per Title II, Article 7, paragraph 1  of the legislation since they do not contain substances that are intentionally released.   This is to ensure compliance with Regulation (EC) No 1907/2006 Title I, Article 3, paragraph 3, the European Union requires registration of chemicals and substances imported into the EU to ensure a high level of protection of human health and environment.
