POSITIVE AIR SHUTDOWN
NO PAS, NO ENTRY!
A positive air shutdown system on your diesel pickups is a must-have upgrade for many mining, forestry, refueling and petroleum contract work
By Bruce W. Smith
It’s a small device that can be held in the palm of your hand, yet it’s the most important safety item on diesel pickups working in or around petroleum production facilities.
If your truck does’t have one, you’re not getting onsite.
The device is called a positive air shutdown system, or PAS.
If you are a contractor who has spent much time around the mining and petroleum-production trades, PAS devices are old hat.
But bring up the subject to the typical construction or landscaping contractor who is trying to expand their business and you’re more than likely to get a blank stare.
Yet having a PAS on a heavy-duty pickup is one of those upgrades that provides a safety benefit like no other aftermarket product out there.
It also opens the doors to getting a contract where such a device is a mandatory component on diesel pickups working where gas vapors pose a safety hazard.
