Petrol COSHH Assessment Form

A pre-filled COSHH Assessment Form for Petrol, with some example text reading:

Spillage and environmental:

Mobility: Store upright and ensure the container is tightly closed. Store in a segregated and approved area. Keep the container in a cool, well-ventilated area. Keep the container tightly closed and sealed until ready for use. Avoid all possible sources of ignition (spark or flame). Store and use only in equipment/containers designed for use with this product. Do not remove warning labels from containers. Ensure lighting and electrical equipment are not a source of ignition.

Accidental release: Do not discharge into drains or rivers. Contain the spillage using bunding, then absorb it into dry earth or sand. Transfer to a closable, labelled salvage container for disposal by an appropriate method. Do not use equipment in the clean-up procedure that may produce sparks.

Petrol, commonly referred to as gasoline in many regions, is a sophisticated blend of hydrocarbons extracted from crude oil. This mixture primarily consists of alkanes, cycloalkanes, and aromatic hydrocarbons, with carbon chain lengths that range from 5 to 12 carbon atoms. The boiling points for these compounds typically fall within the range of 40°c to 205°c, which is crucial for their use as a fuel.

The production of petrol begins with the fractional distillation of crude oil, a process that exploits the varying boiling points of its components. In this method, crude oil is subjected to heating in a distillation column, where it vaporizes and rises through the column. As the vapour ascends, it cools, and different fractions condense at specific heights within the column according to their boiling points. The fraction that condenses between 40°c and 205°c is collected, as it corresponds to the desired range for petrol production.

After initial separation, this fraction undergoes further refining processes, such as hydrocracking and reforming, to remove impurities and enhance its properties. Additives are also incorporated during this refining stage to improve performance characteristics. Notably, octane enhancers are added to increase the fuel’s resistance to knocking during combustion, which is essential for optimal engine performance and efficiency. This meticulous combination of processes and enhancements results in petrol that meets the stringent standards necessary for modern internal combustion engines.
