The fire triangle consists of heat, fuel, and oxygen — removing any one element extinguishes the fire.

Physical barriers and guardrails provide passive, continuous protection that prevents pedestrians from accidentally entering the forklift zone regardless of human behavior.

Regulatory compliance programs are designed to ensure organizations follow applicable laws, regulations, and standards.

Low serum albumin is a common finding in conditions like nephrotic syndrome (due to protein loss), kwashiorkor (severe protein malnutrition), and ascites (due to reduced oncotic pressure). However, serum albumin levels are not a diagnostic marker for esophageal reflux. Esophageal reflux is typically diagnosed based on symptoms, endoscopy, or pH monitoring.

PPE does not eliminate or reduce the hazard — it only creates a barrier between the worker and the hazard, which is why it is considered the last resort in the hierarchy of controls.

Forklift tires are vital for maintaining stability, especially when carrying heavy loads or operating on uneven surfaces. Worn, damaged, or improperly inflated tires can compromise traction, increase the risk of tipping, and affect braking performance. Regular checks ensure the tires provide the necessary grip and support for safe and stable operation, preventing accidents and ensuring efficient material handling.
