(Table to categorise risk Coverted to Text): (1a) IF Probability of Event = Highly Unlikely, and Severity of Harm = Slightly Harmful, then the Risk = Trivial. (1b) IF Probability of Event = Highly Unlikely, and Severity of Harm = Harmful, then the Risk = Tolerable. (1c) IF Probability of Event = Highly Unlikely, and Severity of Harm = Extremely Harmful, then the Risk = Moderate. (2a) IF Probability of Event = Unlikely, and Severity of Harm = Slightly Harmful, then the Risk = Tolerable. (2b) IF Probability of Event = Unlikely, and Severity of Harm = Harmful, then the Risk = Moderate. (2c) IF Probability of Event = Unlikely, and Severity of Harm = Extremely Harmful, then the Risk = Substantial. (3a) IF Probability of Event = Likely, and Severity of Harm = Slightly Harmful, then the Risk = Moderate. (3b) IF Probability of Event = Likely, and Severity of Harm = Harmful, then the Risk = Substantial. (3c) IF Probability of Event = Likely, and Severity of Harm = Extremely Harmful, then the Risk = Intolerable. Note: 'Tolerable' here means risk has been reduced to the lowest level reasonably practicable. Actual table is based on BS8800, Annex D
