Organizations Release White Paper on CNG Refuse Truck Safety

NGVAmerica and the Solid Waste Association of North America have released a where paper on safety and best practices for natural gas-fueled refuse trucks.

Natural Gas: A Clean, Safe and Smart Choice for the Waste and Recycling Industry was released at SWANA’s WasteCon show in Indianapolis last week.

“While natural gas vehicles are as safe as diesel or gasoline powered vehicles,” the paper states, “proper training and maintenance of the vehicles, including all fuel system components and fueling facilities, is required.”

‘Relentless Focus’

“Waste truck fleet operators in both the private and public sectors need to make sure they operate natural gas fueled vehicles safely,” SWANA executive director David Biderman says in the white paper announcement.

“This collaboration is an example of SWANA’s relentless focus on improving the industry’s safety performance in the United States and Canada,” Biderman said.

‘Safety Is Always the Top Priority’

“Safety is always the top priority for NGVAmerica members,” said NGVAmerica technology and development director Dan Bowerson.

The organizations announced their collaboration earlier this summer (F&F, June 13).

The eight-page white paper covers such issues as vehicle operations, fueling, training (including first responder training), facilities requirements, and CNG/compressed natural gas fuel cylinder testing.

WasteCon 2017 has been slated for September 24-27, 2017 in Baltimore.

Blossman Offers LPG Evacuation Pump

August 2, 2016 in New Products, Propane, Safety by Rich Piellisch  |  No Comments

Can Empty Propane Autogas Tanks for Service with Zero Venting

Blossman Services has developed a new pump for removing propane autogas (aka LPG, for liquefied petroleum gas) from fuel tanks, improving safety and preventing loss to the atmosphere. The Propane Autogas LPG Evacuation Pump is said to be the first of its kind for the U.S. market.

The new AutoGas LPG Evacuation Pump from Blossman Services is said to be the first of its kind for the U.S. market.

“This one of a kind, patent pending, Autogas LPG Evacuation System can evacuate a fuel pump-equipped LPI [liquid propane injection] vehicle tank filled to 80% with 44 useable propane gallons in 1.5 hours to zero PSI tank pressure without venting any propane into the atmosphere,” states a release.

Workplace Efficiency

“Autogas fleets and trained autogas technicians now have a service tool available that allows them to safely work on their vehicles on their own timelines,” Blossman says.

The compressed air-powered pump may also be used to transfer propane fuel from one vehicle to another, or to a separate propane storage vessel.

Emcara ‘Garter’ Cap Helps Protect PRDs

June 21, 2016 in CNG, New Products, NGVs, Safety by Rich Piellisch  |  No Comments

‘Garter Vent Cap’ – ‘A Robust Line of Defense’

Emcara Gas Development is promoting a vent cap designed to keep outside water and other foreign matter from impeding the function of pressure relief devices on compressed natural gas fuel systems. PRDs are essential devices that allow gas to vent when pressure becomes dangerously high, as in the case of fire.

“The most common cause of PRD failures is the simple problem of water getting into the outlet lines of the device,” Emcara says. Its answer? The “Garter” vent cap.

‘A Strong Seal’

“The Garter provides a strong seal between itself and the vent line, ensuring that water and other materials do not enter the system, while at the same time staying protected from UV light deterioration, pressure sprays, and other actions that have caused plastic or other caps to fly off or become damaged,” states a release.

The Garter cap is designed with a poppet action to allow gas to escape – it then “quickly re-seals itself.” The Garter cap releases between 5 and 10 psi of pressure, allowing designers to “do away with weep holes, which is another possible area for water to enter the system.”

Safer, Cheaper

Guelph, Ont.-based Emcara Gas Development, Inc. was established in 2010. The firm works to bring new and innovative ideas to the alternative fuels industry with “devices and solutions that increase safety and performance, while reducing overall costs.” Emcara’s product portfolio includes long-trigger PRDs, balanced actuator valves, and ventilation caps.

Further, the company claims a “pipeline of new products in development that will assist in the growth and development of the alternative fuel industry.”

ISL G Engine Safety Recall in Macks

October 27, 2015 in NGVs, Safety by Rich Piellisch  |  No Comments

Some 3,000 Units Affected by Turbocharger Oil Supply Line Issue

Cummins is recalling some 3,000 natural gas-fueled, 8.9-liter Cummins Westport ISL G engines. “These engines have a turbocharger oil supply line that may contact or interfere with the turbocharger inlet elbow, clean air intake clamp, or the air fuel control tube, and result in an oil leak,” says the National Highway Traffic Safety Administration.

“If the turbocharger oil supply line oil leaks in the proximity of the engine exhaust manifold there would be an increased risk of a fire,” says the recall notice.

OEM and Retrofit

The engines in question were manufactured from September 13, 2007, to September 23, 2015, NHTSA says.

“The affected engines were sold for use exclusively in Mack Trucks and Navistar vehicles, both as original equipment and as replacement equipment,” the agency says. The recall applies “exclusively” to Mack trucks.

The total number of engines affected is 2,959. The recall carries NHTSA campaign number 15E085000.

Hexagon Orders: Recent $15 Million

March 11, 2014 in CNG, NGVs, Safety by Rich Piellisch  |  No Comments

‘CNG Is a Great Solution for Transportation,
‘Marketplace Continues to Affirm this Position’

Hexagon Lincoln is talking up $15 million worth of recent new orders for its lightweight Type IV CNG cylinders. The firm is expanding production at its plant in Nebraska and says it will fulfill most of the new orders by year-end.

Separately, a limited number of the firm’s Type IV cylinders have been subject to a safety recall.

HexagonLincoln_CNGtanksHexagon Lincoln is a unit of Norway’s Hexagon Composites.

“It has always been the premise of Hexagon Composites that compressed natural gas is a great solution for transportation and storage of natural gas, and the marketplace continues to affirm this position,” states a release.

Engine technology is improving, the firm says, as is the infrastructure situation, with new fueling stations able to accommodate Class 8 truck fast-fills. “Most importantly,” states the release, “CNG prices are still the lowest available at the pump.”

Back-to-Back Expansions Will Quadruple Production

“When you consider unlimited hold times with no fuel loss, along with the ease in operation of CNG technology, it makes sense to see the market growth,” said Hexagon Lincoln CNG automotive products VP Chet Dawes says in the new orders announcement.

Hexagon Lincoln is working two expansion phases, both of which will double production. The second phase, announced last year as an investment of approximately 150 million Norwegian krone (nearly $25.2 million at current rates), is to be complete next year.

Recall of Smallest CNG Cylinders

Separately, Hexagon Lincoln late last month issued a safety notice affecting “a small number” of its tanks. They are also the smallest in the product line, says company president Jack Schimenti, who told F&F that fewer than 1,000 units are affected. Customers with those small cylinders have received notices advising them to have the tanks professionally purged, and in the meanwhile avoid parking in an enclosed area.

Hexagon will then replace the 14-by-35-inch cylinders.

“The resolution of this issue and replacement of the tanks will proceed as quickly as is prudent but may take up to six months,” Schimenti says in the safety bulletin.

“I sincerely apologize for this inconvenience,” he continued. “I understand the difficulty and disappointment that this action raises.

“However, although this safety concern has occurred in a small number of tanks, Hexagon Lincoln strongly believes in a conservative approach to ensure safety to all involved.”
