Final answer:
Fuel lines on ANFO blending trucks must incorporate safe and efficient components, such as secure hoses, couplings, shutoff valves, and anti-static features, to handle the explosive mixture of ammonium nitrate and fuel oil.
Step-by-step explanation:
Fuel lines on bulk trucks, mix trucks, and ANFO blending trucks must be fitted with components that ensure safe and efficient transport and delivery of fuel. ANFO, which stands for ammonium nitrate/fuel oil, is a bulk explosive mixture commonly used in industries such as mining and construction. Safety regulations often require these vehicles to be equipped with proper fittings to prevent leaks, contamination, and ensure controlled dispensing of fuel to mix with ammonium nitrate. These may include specialized hoses, secure couplings, automatic shutoff valves, and anti-static features designed to handle the hazards associated with ANFO and to prevent accidental ignition or detonation during the blending and delivery process.
