What is D class fire?
Class D fires involve combustible metals, such as magnesium, titanium, and sodium. Extinguishers with a D rating are designed to extinguish fires involving combustible metals. Note: Common extinguishing agents may react with a combustible metal fire causing the severity of the fire to increase.
How many standpipes does a 6.0 Powerstroke have?
A set of two each: High Pressure Oil Stand Pipes and Dummy Plugs for the Ford 6.0L Diesel.
