Hydrogen sulfide detectors can help you recognize when you encounter the toxic gas. Known as the foul smell reminiscent of rotten eggs, H2S can be recognized by its smell, but possessing H2S detection equipment can narrow down where the odor originates, keeping your company and employees safe. About half the population can smell it at concentrations of eight parts per billion (ppb), and 90% can smell it at 50 ppb. But even small amounts of H2S can be harmful.

The position of the H2S detector is vital. Placing it in the incorrect location can prevent early detection. It should be placed near air currents where you're monitoring the gas in question. Your employees are counting on you to locate the toxic gas, eliminating it from the air. Before you can mount the H2S detector you decide upon, consider the following:

1. Purchase hydrogen sulfide detectors from wholesalers in bulk.

2. Find portable H2S detectors if you travel to different buildings frequently.

3. Buy a hydrogen sulfide detector that also identifies other toxic gases.

Action Steps
The best contacts and resources to help you get it done

Buy H2S gas detection equipment in bulk from wholesalers

Purchase H2S detectors in bulk to reduce costs. Buying in bulk is best if you work in a business that requires many hydrogen sulfide monitors, such as if you own multiple refineries, waste water facilities or offshore platforms.

I recommend: General Monitors can supply your facility with H2S detectors for a reduced cost if you purchase in bulk. Pem-Tech is another option, as it carries a detector (hydrogen sulfide) with a weatherproofing cover.

Purchase a portable hydrogen sulfide gas detector

Portable H2S gas detection is useful if you travel in and out of buildings, checking for toxic gas leakage. It's ideal for use by those companies wanting advanced performance, reliability and ease of use without the high costs of long-term maintenance. Some portable options don't require battery charging, making them even easier to carry around since you're not forgetting them on the charger.

I recommend: Look at Professional Equipment and its list of easily maintainable H2S detectors. Major Safety Service is committed to selling top-quality, portable hydrogen sulfide detectors.

Reduce clutter and cost, and bundle your H2S detector with one that includes other detectors

If your facility monitors H2S in addition to other toxic gases, multi-gas detectors are the best monitors to purchase. Most companies offer detectors that locate several toxic or nontoxic gases, with the popular four-gas monitors. Hydrogen sulfide, carbon monoxide, combustible gases and oxygen comprise these four gases. Usually these monitors are a little more expensive, but remember that they monitor more than one gas, in essence saving you space--since you're only dealing with one monitor instead of four--and money in the long run.

I recommend: Optimum Energy Products sells multi-gas detectors, including a standard four-gas monitor. Web Soft Safety Solutions sells both portable and stationery multi-gas detectors. All Gas Detectors carries several brands of multi-gas detectors, some that can run for 16 to 20 hours straight.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Hydrogen sulfide is heavier than air, so it's best to install H2S gas detectors lower to the ground. Outdoors, it accumulates in concentrations that can kill livestock, wildlife and even humans.
