The new PHE guidance states personal protective equipment, such as masks, can protect against potentially fatal exposure to the drug.
First responders should also ‘avoid actions that could cause powder to become airborne’, but it did not specify any further as to what they may be.
Skin contact with fentanyl is unlikely to lead to harmful effects – especially if the skin is washed promptly with water, officials said.

First responders may encounter fentanyl at ambulance calls for an overdose, traffic stops, arrests and even random searches.
