Danger:
Steel squeegees have particularly sharp edges. There is an increased
risk of injury to the hand or lower arm when fitting/removing these
components. Always follow the recommended sequence of fitting/
removal steps, and wear protective gloves.
Danger:
Inhaling flux vapour may cause allergic reactions. Lead on the hands
can enter the body when a person is eating, smoking or drinking, or
when the hands touch mucous membranes.
Preventive measures:
Do not store solder paste in open containers and do not leave solder
paste residue in the printer if it is not being used.
Always make sure that sufficient vapour extraction is provided. Do
not touch mucous membranes with contaminated hands.
Other hazards
Danger:
Solder paste is a tin-lead alloy with a rosin-based fluxing agent.
Birth defects are possible if pregnant women who come into contact
with solder containing lead fail to observe the personal hygiene rec-
ommendations.
Preventive measures:
Where possible, ensure that adequate vapour extraction is provided.
Do not allow vapours to be produced. Do not allow the solder paste to
overheat in the machine.
Always wash hands before eating, smoking and drinking. Do not
allow solder paste to come into contact with skin. Change contami-
nated clothing.
