2. Sterilant gas monitoring - Wikipedia

   en.wikipedia.org/wiki/Sterilant_Gas_Monitoring

   The odor threshold for these gases is above the PELs and for ethylene oxide it is 500 ppm, approaching that of the IDLH. [1] Odor is thus inadequate as a monitoring technique. Continuous gas monitors are used as part of an overall safety program to provide a prompt alert to nearby workers in the event that there is a leak of the sterilant gas ...

3. Short-term exposure limit - Wikipedia

   en.wikipedia.org/wiki/Short-term_exposure_limit

   The Occupational Safety and Health Administration (U.S. OSHA) has set OSHA-STELs for 1,3-butadiene, [1] benzene [2] and ethylene oxide. [3] For chemicals, STEL assessments are usually done for 15 minutes and expressed in parts per million (ppm), or sometimes in milligrams per cubic meter (mg/m 3 ).

4. Immediately dangerous to life or health - Wikipedia

   en.wikipedia.org/wiki/Immediately_dangerous_to...

   The OSHA definition is arguably broad enough to include oxygen-deficient circumstances in the absence of "airborne contaminants", as well as many other chemical, thermal, or pneumatic hazards to life or health (e.g., pure helium, super-cooled or super-heated air, hyperbaric or hypo-baric or submerged chambers, etc.).

5. Workplace hazard controls for COVID-19 - Wikipedia

   en.wikipedia.org/wiki/Workplace_hazard_controls...

   According to OSHA, medium exposure risk jobs include those that require frequent or close contact within six feet (1.8 m) of people who are not known or suspected COVID-19 patients, but may be infected with SARS-CoV-2 due to ongoing community transmission around the business location, or because the individual has recent international travel to ...

6. Sterilization (microbiology) - Wikipedia

   en.wikipedia.org/wiki/Sterilization_(microbiology)

   Ethylene oxide treatment is the most common chemical sterilization method, used for approximately 70% of total sterilizations, and for over 50% of all disposable medical devices. [ 26 ] [ 27 ] Ethylene oxide treatment is generally carried out between 30 and 60 °C (86 and 140 °F) with relative humidity above 30% and a gas concentration between ...

7. Mechanical filter (respirator) - Wikipedia

   en.wikipedia.org/wiki/Mechanical_filter_(respirator)

   UVGI (an ultraviolet method), ethylene oxide, dry oven heating and vaporized hydrogen peroxide are currently the most-favoured methods in use in hospitals, but none have been properly tested. [58] Where enough masks are available, cycling them and reusing a mask only after letting it sit unused for five days is preferred.

8. Occupational Safety and Health Administration - Wikipedia

   en.wikipedia.org/wiki/Occupational_Safety_and...

   Examples of OSHA standards include requirements for employers to provide fall protection such as a safety harness/line or guardrails; prevent trenching cave-ins; prevent exposure to some infectious diseases; ensure the safety of workers who enter confined spaces; prevent exposure to harmful chemicals; put guards on dangerous machines; provide ...

9. Ethylene oxide - Wikipedia

   en.wikipedia.org/wiki/Ethylene_oxide

   Ethylene oxide scrubber: After the gaseous stream from the main reactor, containing ethylene oxide (1–2%) and CO 2 (5%), is cooled, it is then passed to the ethylene oxide scrubber. Here, water is used as the scrubbing media which scrubs away majority of ethylene oxide along with some amounts of CO 2 , N 2 , CH 2 =CH 2 , CH 4 and aldehydes ...
