My company has recently began issuing laptops to workers for use outside of the office. I have been given the task of developing the policies for their use. I want to include a policy about how long an employee is allowed to leave a laptop in their vehicle during hot or cold conditions. My initial response is that they never should because I know the damage that can be caused extreme temperatures. However, in their line of work, it is sometimes unavoidable. So, I have to come up with guidelines of what may be acceptable when it is absolutely necessary. I have researched the internet but have been unable to find any research about how long it takes for damage to occur. Any facts or suggestions would be very helpful.
