While cleaning effect with diesel is good, the low flash point and continuous exposure of the personnel to the nauseating odour of diesel renders the working environment vulnerable. Apart from the known symptoms such as irritation to skin and eyes, continuous exposure to diesel without safety gear can affect central nervous system, immune and hormonal systems in adults.
Continuous exposure to kerosene is known to cause irritation to eyes and skin in humans. Studies have shown that chronic exposure to kerosene can result in drowsiness, irritability, restlessness and even convulsions. Flash point of kerosene varies between 23°C to 61°C.
Owing to their low flash points and associated safety concerns, authorities in many countries prohibit and dissuade industries from using diesel and kerosene as a cleaning.
