Is it as much a hazard as it is being portrayed? If the conditions are
hot enough that people are uncomfortable wearing smocks, they probably won't
be wearing long sleeve shirts that can dangle in what you're working on. In
fact, they are probably wearing the least they can get away with at their
place of employment - tank tops and shorts if allowed. If they wear a
static strap, and heel strap, are they really in that much ESD risk? They
might be at more risk for safety issues - solder splashes, cuts, etc., than
ESD issues.

Jim,
Higher humidity can lower the ESD risk but have them wear the smocks to
be safe.
Besides the humidity levels, it depends on what your operators are
wearing. Cotton, polyester or nylon have different triboelectric
properties so build up charge at different rates and amounts. Think about
how much static builds up on your polyester socks versus your cotton socks
in your clothes dryer at home.

Good day Technetters:
I need some opinions (this may be asking for trouble!). Located in
the
north east, temperature/humidity levels can change on a daily basis.
It has
been our policy that, during summer months when the humidity is high,
the
operators do not have to wear ESD smocks in areas that are not air
conditioned. There is no hard fast rule as to what the conditions
shall be,
except that a decision is made (by yours truly) that smocks are
optional
when conditions are uncomfortable. I'm trying to select a specific
humidity
level to use as a criteria for the mandatory wearing of smocks. I
understand that not wearing ESD smocks poses a risk, but the risk is
minimized during high humidity conditions. What do you think of this
policy? Any recommendations on a humidity level?
Thanks,
