Identify a major hazard when working around diesel engines and one key safety practice.

Prepare for the Engineman EN A School Test 1. Utilize flashcards and multiple choice questions with detailed explanations to boost confidence and readiness for the test.

Hazards around a diesel engine include hot surfaces, fumes, and moving parts, which can cause severe burns, respiratory irritation, or entanglement. The best safety practice is to isolate the machine and apply a lockout/tagout so it cannot start during maintenance, while wearing proper PPE such as gloves, eye protection, and appropriate clothing. Lockout/tagout addresses the primary risk by preventing unexpected energization or release of stored energy, especially near belts, fans, and hot components. PPE provides an essential protective layer against incidental contact and exposure. While noise or dust can be concerns, they don’t tackle the core danger of the engine starting or energy being released during servicing.
