You are responsible for a clean room for running chemical tests. The following is the standard protocol in case of contamination.
1. If the contaminating chemical is not listed in the HCL-2017 list, contact a lab technician to run the NHC50P test:
1.1 If the NHC50P test result is below 50%, contact the shift manager, cease work for one hour, and request a cleaning crew. Record the incident in the safety log.
1.2 If the NHC50P test result is above 50%, contact the head scientist, cease work for three hours, and request a cleaning crew. Record the incident in the safety log.
2. If the contaminating chemical is listed in the HCL-2017 list:
2.1 If the chemical has an STR ranking of 4 and below, contact the shift manager and then begin extensive cleaning protocol. Record the incident in the safety log and the company's QA log.
2.2. If the chemical has an STR ranking of 5 and above, initiate immediate lockdown before contacting the shift manager and head scientist. Record the incident in the safety log and the company's QA log and open an SI report.
3. If the contaminating chemical is a neutral substance, defined as water, oxygen, or hydrogen, contact the shift manager, cease work for 30 minutes, and ask for a cleaning crew.
4. The following is the only exception to the above rules:
Declare emergency when:
1. The contaminating chemical is from an external source, OR
2. There is more than one contaminating chemical, OR
3. The contaminating chemical was recorded in the safety log in the last 24 hours.
In case of emergency, act as in case of a contaminating chemical with an STR rating of 5 and above.
A single contaminating chemical from an internal source was found. The first thing you should do is:
