Electrical fires are another common laboratory hazard, which can occur when incorrect or unsafe cords and plugs are used.
Future versions of this technology might allow clinicians to detect current infections. The technology is new and the evidence for its accuracy in coronavirus diagnosis is still being evaluated. Testing levels of antibody in blood allows a single patient sample from one accessible part of the body where sampling is non-invasive to be tested for presence of virus. A control line must appear to show that the assay has worked correctly. Antibody lateral flow immunoassays detect antibodies to the virus in the blood.

Keeping up-to-date, accurate chemical storage records is also a core element of ensuring total chemical safety on site. Keeping chemical storage records is necessary not only to meet regulatory compliance but also to ensure employee safety and efficient inventory management.
