Refinery Safety
Wear the Tango H2S monitor closest to this on the lapel of your FRC.
What is your breathing zone?
Secure cylinders in racks provided with these to prevent falling.
What are a cylinder straps or chains?
Cloudiness or wisp-like structures floating or suspended in the liquid. If any of these signs are present, further inspection is required and the material should not be disturbed.
What are the preliminary signs of peroxide formation?
Bases should never be stored with these.
What are acids?
Prudent practice is to check this each shift for peak exposure; monthly recalibration at a minimum, and after it alarms is also required.
What is your Tango monitor?
These gas cylinders shall not be stored near highly combustible material, especially oil and grease; or near reserve stocks of carbide and acetylene or other fuel-gas cylinders, or near any other substance likely to cause or accelerate fire.
What are oxygen cylinders?
If a peroxide forming compound has been stored either beyond its useful shelf life or safe storage time/testing frequency, or if its age or history can not be determined, it is considered this and shall be quarantined.
What is explosive?
Keeping your work area clean; this is essential to safety and is an asset to efficiency.
What is good housekeeping?
What is 2 injuries.
These samples present a significant H2S hazard as the concentration of H2S in these samples can exceed 40%.
What are vent gas samples?
What is D-1?
A fume hood or other appropriate exhaust ventilation used when handling peroxide forming chemicals in a manner that may produce an airborne hazard is are examples of these type of controls.
What are Engineering Controls?
Once it is used, take it out of service and replace it with a fully charged one.
What is a fire extinguisher?
Calibrated for monitoring LEL, O2, H2S, CO, this is located in the main hallway and can be used to monitor the area of exposure in the event an H2S monitor alarms.
What is the Altair Gas Tester?
Before bringing a cylinder into the lab, while the cylinder is secured, crack open the valve momentarily to blow out dust from the cylinder outlet. Close the valve hand tight to also insure this.
What is that the valve will not fail in the open position inside the building?
Peroxide formation in common lab chemicals is caused by this.
What is an oxidation reaction?
The Compressed Gas Association (CGA) has standardized various cylinder valve outlets for different families of gases to prevent the interchange of regulator equipment among these.
What are gases that are not compatible?
The Hazard Communication Standard (HCS) requires these on labels to alert users of the chemical hazards to which the may be exposed. One example is the exclamation point.
What are pictograms?
The following are some ways to minimize the potential for this
• know which samples are expected to contain high levels of H2S (> 10 ppm)
• look at the LIMS label for the phrase, “Danger, Contains H2S”
• handle samples in the hood
• avoid reaching too far inside the hood to prevent exposure
• wear the H2S monitor closest to your breathing zone on the lapel of the FRC
• maintain the hood doors at the appropriate working height
• dispose H2S-containing samples one at a time
What is H2S exposure?
Cylinders are to be moved only with these in place, hand tight.
What are the valve protective caps?
When a peroxide-forming compound is purchased and received by the lab, it will be labeled with this.
What is a Peroxide-Forming chemical label?
To reduce the chance of a hood fire, do not store these in any hood where samples are heated (flash or distillation hoods).
What are solvents or samples?
