New regulations in regards to requalifying cylinders

Posted on January 23, 2017 at 3:00 PM Comments comments (0)

Two new regulations for re-qualification of cylinders will become mandatory starting Monday - January 23, 2017.


New Re-qualification period for DOT4 series cylinder such as Propane




Option to now use test labels rather than stamps on all cylinders, except for 3HT series.


Section 180.209(e) of 49CFR

(e) Proof pressure test. A cylinder made in conformance with DOT Specifications 4B, 4BA, 4BW, or 4E protected externally by a suitable corrosion-resistant coating and used exclusively for non-corrosive gas that is commercially free from corroding components may be requalified by volumetric expansion testing or proof pressure testing every 10 years instead of every 5 years. When subjected to a proof pressure test, the cylinder must be carefully examined under test pressure and removed from service if a leak or defect is found.

This is a rule change, previously Propane 4B specification cylinders were requalified by:

- Volumetric Test every 12 years

- Proof Test every 7 years

- External Visual Examination every 5 years


With this rule change, Propane 4B specification cylinders are now requalified by:

- Volumetric Test every 10 years

- Proof Test every 10 years

- External Visual Examination every 5 years


Section 180.213(c) of 49CFR

(c) Requalification marking method. The depth of requalification markings may not be greater than specified in the applicable specification. The markings must be made by stamping, engraving, scribing, or applying a label embedded in epoxy that will remain legible and durable throughout the life of the cylinder, or by other methods that produce a legible, durable mark.


Previously the use of labels to mark the re-qualification information on a cylinder was only permitted on Composite cylinders and fire extinguishers. This rule change now allows labels to be used on all cylinders except the 3HT cylinder which specifically states you must use Low Stress stamps.


2016 ERG Guide Correction

Posted on November 18, 2016 at 5:15 PM Comments comments (0)

An issue has been found with the 2016 ERG’s that were part of the first batches printed. 


On page 13, ROAD TRAILER IDENTIFICATION CHART, Compressed Gas/Tube Trailer, gives a guide page of 137. This is incorrect and should state Guide 117. This was discovered and reported several months ago and apparently this issue  was corrected in the latest printed versions of the ERG.


Please make sure your personnel are aware of this issue when utilizing the ERG’s.


Changes to the New 2016 Emergency Response Guidebook

Posted on September 12, 2016 at 12:20 AM Comments comments (0)

If you’re a first responder, or involved with Hazardous Materials in any way, you should be familiar with the Emergency Response Guidebook (also known as the ERG or Orange Book). The 2016 edition was released this year with some significant from the previous 2012 version. The current changes are:

-The addition of a flow chart the describes “How to use the Guidebook”

-A area has been included for local emergency response numbers to be written in.

-A section has been added for the Global Harmonization System (GHS) of classification and labeling of chemicals.

-Addition of all new dangerous goods listed in the UN Recommendations on the Transport of Dangerous Goods up to the 19th revised edition.

-In the table of initial isolation and protective action distances (Green Pages) there is the addition to table 3 of “Estimating wind speed from environmental clues”.

These changes definitely improve the ERG and make initial responses actions safer. I highly recommend any user of this manual pick up the latest copy and flip through it for familiarization or review.


Potential Inclusion of CGA C-1 into 49 CFR

Posted on September 8, 2016 at 11:50 PM Comments comments (6)

If you are a facility that hydrotests compressed gas cylinders, you need to read this. The Pipeline and Hazardous Materials Safety Administration (PHMSA), is proposing to amend CFR Title49, section 180. This is the section that pertains to cylinder re-qualification.

A petition from the Compressed Gas Association (CGA) and others to incorporate the Pamphlet C-1 into the regulations is being considered and recommended by the PHMSA. If this happens, this regulatory change will adversely effect the safety of this industry and add an unnecessary monetary burden to all DOT licensed facilities.

What Does The Inclusion of The C-1 Pamphlet Mean To DOT Licensed Cylinder Re-Qualifiers ???


At a Minimum:

• New expansion indicating (EID) components

• Additional pressure gauges (PID)

• Additional calibrated cylinders

• New test record forms or software

• Training to understand these new regs.

• Mobile re-test facilities ( fire extinguisher mobile shop) will be limited to a 100 mile radius.


• Comments close on September 26th, 2016.

• All cylinder retest facilities need to read the Proposed Regulations.

• Please Make Comments - This Is Your Business !!

• Whether you agree with PHMSA or not, you need to make your opinion known. See Federal Register, Page 48978 for how and where to make comments.

• This is Your Business - Do Not Let Proposed Regulations Get Passed Without Your Input.

Possibile Scuba Cylinder Rupture in Australia this week

Posted on August 25, 2016 at 4:30 PM Comments comments (0)

As some people may have heard, there is the report of the rupture of a recreational SCUBA cylinder in Sidney, Australia this week. Preliminary reports are that the cylinder was being filled at a recreational dive shop, and one individual was injured. Contrary to the assumptions and speculations that are circulating on online forums, as of now, no official report or findings have been published in reference to the type of cylinder, and cause of the rupture. If the reports of the injury are factual, our hearts go out to the individual who was injured and wish him/her a speedy recovery. More information will be posted as it comes available.

The Hazards of Falsely Certifying Compressed Gas Cylinders

Posted on January 16, 2016 at 6:10 PM Comments comments (0)

When an owner drops off a cylinder to be re-qualified, they expect that the hydrotester will not cut corners. After all, when a cylinder ruptures, 90% of the time, it’s during the filling process and usually it is the owner filling it. They expect the test to be accurate because it is their own safety on the line. But what happens if the hydrotester they take the cylinder to cuts corners during the test. Or even worse, what if the tester stamps the tank and falsifies the records without even testing the tank? Well..the Pipeline and Hazardous Materials Safety Administration (PHMSA) takes a dim view of this. The fines can be pretty steep if the hydrotester is found in violation. Take for example what happened in California this last fall. On October 29, 2015, Danniel Allen Hoose, of Redding, California, was sentenced in U.S. District Court, Sacramento, California, related to falsely certifying oxygen cylinders for aircraft. He was sentenced to 36 months' probation and ordered to pay a fine of $3,000. He pleaded guilty in July 2015 to one count of falsely certifying more than 570 oxygen cylinders for re-use, including re-use in aircraft. In the spring of 2013, Hoose represented that he performed hydrostatic testing on a special permit oxygen cylinder installed in an aircraft. But, no such testing was done. The investigation determined that Hoose's re-qualification equipment was in disrepair so he was unable to properly test the cylinders in accordance with Pipeline and Hazardous Materials Safety Administration (PHMSA) regulations. Hoose falsified the cylinder hydrostatic testing certifications and returned the cylinders to their owners for use.

New GHS/HAZCOM Enforcement Guidence

Posted on August 21, 2015 at 5:35 PM Comments comments (0)

As you should be aware by now, the USA is transitioning over to the new Global Harmonization System/Hazardous Communication Standard. (GHS/HAZCOM) This new standard is designed to bring the US onto the same system used by other members of the UN and global community.  It includes new standards on Safety Data Sheets, labels, and placards/symbols.  The changeover period is a 4 year transition starting in December 2012.  Unfortunitly, durring this transition period, there has been some questions on what standards OSHA will inforce durring an inspection.  In june this year, OSHA finnally clarified this by issuing a new directive for the enforcement of the new GHS standard. To summarize, during the transition period to the new 2012 GHS standard, the goal is to establish consistent policies and procedures to ensure uniform enforcement of the hazard communication standard. It also provides inspectors with a detailed review of the areas they will be inspecting, including revised hazard classification of chemicals, standardizing label elements for containers of hazardous chemicals, and specifying the format and required content for safety data sheets, and how chemical users should manage their MSDS/SDS library. MOST IMPORTANTLY, it states that inspectors can use both the old standard, and the new standard to issue violations.  If you need a copy of this directive, email me at [email protected]

Storing Compressed Gas Cylinders in the Workplace

Posted on June 12, 2015 at 9:10 AM Comments comments (0)

Do you store compressed gas cylinders in your workplace? The odds are, you probably do. Compressed gasses are used in industries ranging from aviation to beverages, to welding. Hundreds of different materials are packaged in compressed gas cylinders to include atmospheric gases, fuel gases, refrigerant gases, poison gasses, and gasses used for industrial use. In most cases, no matter what the material stored, the standards for safety remain the same. The hazards associated with these gases can include oxygen displacement, explosion and flammability hazards, toxicicity and the physical hazards of a ruptured cylinder.

When it comes to workplace safety with compressed gasses, you can find the requirements in 29 CFR 1910.101. One of the easiest, yet most often ignored safety measures is the visual inspection of cylinders. Per 29 CFR 1910.101(a) employers must inspect the cylinders to ensure that they are in a "safe condition".

Visual and other inspections must be conducted as described in the Department of Transportation (DOT) hazardous materials regulations (49 CFR 171 - 179). Cylinders are required to be inspected at time of hydrostatic requalification. In addition, may manufacturers recommend at least an annual visual inspection in addition, or depending on the use, a visual inspection at even shorter time intervals.

Where the DOT regulations are not applicable, visual and other inspections must be conducted as prescribed in the Compressed Gas Association's C-6 standards for visual inspection of steel compressed gas cylinders, C-6.1 for visual inspection of aluminum compressed gas cylinders, C-6.2 for visual inspection of fiber reinforced compressed gas cylinder, and C-8 standard for requalification of DOT-3HT, CTC-3HT and TC-3HTM seamless steel cylinders pamphlets.

It is recommended that employees receive visual inspection training from a recognized training agency such as Professional Scuba Inspectors- Professional Cylinder Inspectors, INC (PSI-PCI).

Gas cylinder storage and handling also has its own set of guidelines and regulations. Per 29 CFR 1910.101(b), the facility handling, storage and utilization of all compressed gas cylinders must be in accordance with CGA Pamphlet P-1 Safe Handling of Compressed Gas Cylinders.

When being stored, gas cylinders should be properly secured at all times to prevent tipping, falling or rolling. They can be secured with straps or chains connected to a wall bracket or other fixed surface, or by use of a stand or cylinder cage. In addition, if the cylinders hold pure oxygen or flammable gas, they must be mechanically grounded in order to prevent ignition.

Additionally, the gas cylinders should be stored in a cool, dry, well-ventilated, fire-resistant area that meets all applicable federal, state and local regulations. It is also recommended that the appropriate NFPA 702 diamond be posted in order to assist first responders in the event of a fire.

When a gas cylinder is empty or not being used, ensure that the valve is closed, the regulator removed and that the valve protector cap is secured in place. Cylinders that are out of hydro or are empty should be properly labeled/placarded, and segregated from those in use.

When transporting cylinders you should us hand trucks designed for that purpose. Don’t roll them in order to prevent damage. When transporting by vehicle, cylinders should be secured so that they do not tip, fall, roll, or potentially fall from the vehicle Please check with your state to determine the requirements for placarding and labeling the vehicle when transporting.

Appropriate lifting devices, such as cradles or nets must be used when using a crane, hoist or derrick to transport gas cylinders. Do not use magnets or slings to lift gas cylinders. Do not use the valve protection cap for lifting a gas cylinder.

It is necessary to take precautions so that gas cylinders are not dropped or allowed to strike each other or other objects. Dropping or striking may damage the gas cylinder valve, which could turn the gas cylinder into a dangerous torpedo with the potential to destroy property and/or injure and kill personnel.

Consult the appropriate safety data sheet (SDS) and cylinder label for detailed information on the chemical contained in the gas cylinder. Specific chemical handling and storage precautions will be outlined in the SDS. The SDS will also have specifications for appropriate personal protective equipment for worker protection. Remember, while cylinders all have the same physical hazards associated with them, the material inside might have additional hazards that you must be aware of.
