Servicing tires with the high pressure side of a nitrogen cart is authorized as long as the appropriate PPE is worn.

• A. True
• B. False
• C. Only with supervisor approval
• D. Only if tire is under 20 psi

Answer: (B)

Using the high pressure side of a nitrogen cart to service tires is not authorized, even with PPE, because PPE cannot eliminate the hazards of high-pressure gas. The high-pressure outlet is designed for charging or testing, not for inflating tires. A failure or rupture in that path can release gas at thousands of psi, causing severe injury or damage. Tire inflation requires a regulated, low-pressure outlet with proper controls, gauges, and safety features, accessed through equipment and procedures specifically intended for tire servicing. Therefore, you should use the low-pressure, regulated side (or a dedicated tire inflation system) and follow the established safety procedures.
