[On_site_list] JLab Stage 2/3 Heat Advisory for week of July 19

[deborah magaldi]

All this week, National Weather Service forecasts for areas across 
eastern Virginia call for daytime temperature and humidity to produce 
Heat Index values above 100 degrees Fahrenheit. These are potentially 
dangerous conditions, and call for implementing Stage 2 and possibly 
Stage 3 severe heat responses listed in ES&H Manual Chapter  6670, 
Appendix T1 Heat Stress Work Cessation Procedure at: 
http://www.jlab.org/ehs/ehsmanual/6670T1.htm .

Please use caution if working outdoors, in areas without air 
conditioning or if conducting strenuous work, and contact Industrial 
Hygiene at ext. 6381 for fluid replenishment drinks and to conduct heat 
index measurements local to your work environment. Local measurements 
can help identify a work/rest regimen that will help you work more 
safely in the heat.

Peak temperatures will run from 1-5 p.m. each day. Plan outdoor work for 
early morning. Stay indoors with air conditioning whenever feasible. If 
working outdoors or in areas not air conditioned:
--Plan adequate rest breaks,
--Wear protective clothing and sun screen and
--Drink plenty of hydrating fluids. Thirst lags behind dehydration. 
Drink more than your sense of thirst indicates.

If you engage in lunchtime sports activities (jogging, street hockey, 
walking, bicycling, etc.) adjust your activity level and stay well 
hydrated. The EH&S Manual calls for lab staff to curtail voluntary 
athletic activities when the Heat Index exceeds 93 degrees F.

If you feel ill or begin to experience heat stress symptoms, contact 
Occupational Medicine promptly at ext. 7539.
