How to manage Aspiration Hazard on New Formpak
The criteria for a substance meeting the Aspiration hazard criteria (Aspiration Hazard Category 1 and carrying H304) can be summarised as those substances:
Regarding the viscosity quoted, this is quite thick, so practically speaking, most hydrocarbons would be classified with Aspiration Hazard Category 1. Mixtures containing 10% or more hydrocarbons must also be classified in this way.
Brief Description of Set up on Formpak:
To every simple raw material which meets the criteria of Aspiration hazard due to being a hydrocarbon, add the hazard AH 1 = Yes (In GHS Hazards Property Group). When you ‘Calculate Now’ you will see HC% is calculated as 100%.
Complex Raw Materials will get a hazard calculation based on the simple materials within them. If there is 10% or more AH 1 components, then AH 1 and a HC% is attributed. However, if the aspiration hazard is not appropriate because the product is solid or very viscous, then it’s possible to manually alter. Follow the usual method to do this.
