The Best Online Program—Hydrogen Sulfide (H2S) Awareness Course

H2S Training Online Training | Hydrogen Sulfide Safety Training Course

What is Hydrogen Sulfide?

A colorless, combustible gas with a “rotten egg” smell, hydrogen sulfide is very dangerous. Officially known as dihydrogen sulfide, it is often referred to as hydrogen sulfide, swamp gas, sour gas, or sewage gas. In this article, it will be referred to as H2S or hydrogen sulfide interchangeably.

H2S can be produced when bacteria break down organic materials, such as animal and human waste. It is mostly produced in sewage and oil, but it may also happen anywhere there is a lot of biodegradation. Drilling and refining natural gas and petroleum, as well as the treatment of wastewater, coke ovens, tanneries, and paper mills are industrial processes that can create hydrogen sulfide. Additionally, hydrogen sulfide can exist as a compressed liquid.

Although sewers and wastewater treatment facilities are also frequently the site of hydrogen sulfide occurrences, oil activities are where it is most frequently discovered. Due to the bacterial decomposition of organic materials, exposure to H2S can also happen in wetlands, agricultural silos, and pits. Pulp, paper, and food processing, hot asphalt paving, mining, and other textile sectors are other occupations where there may be a danger of exposure.

Why Do You Need Hydrogen Sulfide Training?

When people are exposed to hydrogen sulfide gas, terrible things can happen. H2S is poisonous to humans. This gas has effects similar to cyanide or carbon monoxide. Personnel in the gas and oil industries come into daily contact with this gas. Government restrictions limit the amount of H2S workers can be exposed to, but exposure isn’t the sole concern.

H2S is extremely explosive and can put employees at risk in various ways. It’s crucial to be cautious while using any electric, gas, or other tools that might produce a spark in places where H2S is prevalent. Depending on the circumstances, H2S can kill within minutes and is harmful to the body.

Air is less dense than H2S. This poses a serious risk since it will settle in lower places, displacing air and obstructing the flow of oxygen. Employees who are exposed to H2S face particular risks in tight spaces, pits, trenches, and poorly ventilated areas. Due to the possibility of H2S exposure, all employees must complete the H2S alive training course in order to verify that the correct procedures are followed.

Hard Hat Training Online Course

It is essential to learn how to avoid or reduce exposure to H2S. One reason is that the gas cannot be seen by humans, and even if it may smell strongly, it can still be lethal or extremely harmful when taken in small doses. Often, by the time you smell the rotten-egg smell, you’ve already absorbed some H2S into your respiratory system.

Although the scent of H2S may be detected in even the smallest doses, prolonged exposure to the gas can make the body less sensitive to its fragrance. When this happens, the exposure develops into a dangerous medical condition called “olfactory (smell) desensitization”. There is no longer a natural biological warning mechanism for detecting the presence of H2S after a person loses the ability to sense the gas.

Workers must learn how to identify hydrogen sulfide since it reacts so fast and has a significant influence on the human body. This includes instruction on the use of wearable sensors that can detect minuscule quantities of H2S and raise an alarm far in advance of the gas building up to hazardous levels. Knowing what to look for when selecting trustworthy monitoring equipment is crucial. Wireless devices that send data to monitoring teams so they can respond when an exposed person goes unconscious, as well as factors like reliable construction and rapid response, are crucial.

Never forget that any workplace with an H2S risk will have particular protocols, emergency procedures, and PPE onsite. Training in identification and treatment is required for anybody who works in a setting where H2S gas might be present. Knowing when the gas is nearby is insufficient. Additionally, it’s critical to understand what to do if a coworker is exposed and unable to leave the risk area.

Can Hydrogen Sulfide Training Be Done Online?

Yes! At Hard Hat Training we offer a Hydrogen Sulfide Awareness training course that may be done totally online, allowing employees to move at their own pace.

Does OSHA Require H2S Training?

Hydrogen sulfide exposure addressed in specific OSHA Requirements for general industry, maritime, and construction. This section highlights OSHA Requirements and documents related to hydrogen sulfide.

There are 29 OSHA-aligned State Plans operating state-wide occupational safety and health programs. State Plans are required to have standards and enforcement programs that are at least as effective as OSHA’s and may have different or more stringent requirements.

Health and Safety Risks

Many health issues are brought on by hydrogen sulfide gas. The main method of hydrogen sulfide exposure for workers is breathing it in. The consequences vary depending on how much and for how long workers breathe hydrogen sulfide. Extremely high exposure levels have the potential to be fatal.

What about the longer-term effects on worker’s health?

Hydrogen sulfide is both an irritant and a chemical asphyxiant. Depending on the extent and length of exposure, different health impacts may be experienced. Even at levels that were previously accepted as not having an impact, repeated exposure can cause health problems.

Low quantities cause irritation of the eyes, nose, throat, and respiratory system (coughing, shortness of breath, etc.). When working in low-level concentrations, the effects may not be felt for several hours or even days. Frequent or protracted exposure may result in eye irritation, headaches, exhaustion, irritability, sleeplessness, digestive problems, and weight loss.

High concentrations can result in shock, convulsions, difficulty breathing, unconsciousness, coma, and even death. Effects could start after a few breaths or perhaps just one. Most workers exposed to such a high concentration can also experience headaches, impaired memory, and motor function. There have also been reports of issues with the cardiovascular system at exposure levels over permitted exposure limits. Asthmatics can be particularly vulnerable to hydrogen sulfide exposure.

More severe eye and respiratory irritation, including coughing, breathing difficulties, and fluid buildup in the lungs, as well as headache, dizziness, nausea, vomiting, stumbling, and excitability, can be brought on by moderate exposure.

Online Safety Training FAQs

What does each online class cover?

Generally speaking, each course covers the following: 1. Overview of the Course/Introduction to the Equipment 2. Anatomy, including pre-shift inspections 3. Stability Principles 4. Common Hazards/Accident Profiles 5. Safe Operation 6. Rigging and Hand Signals (for crane courses only).

How long is the course?

Trainees go at their own pace, but in general each class (including the exam) takes anywhere from 2 to 2.5 hours. We recommend planning for two or more so you don’t end up rushing through the exam.

Are these courses OSHA-aligned?

All of our Hard Hat Training online courses were built and continue to be updated by our trainers and inspectors using OSHA and ANSI guidelines. But it is important to understand that by OSHA-aligned, we mean it follows to the best of our ability the best practices and safety principles put forth by OSHA. In an online format, it is not possible to cover every code for every situation or hazard across every industry. For this reason, our safety training solutions are tools to further knowledge and help employers train and/or certify their crew. But just because a course or program is OSHA-aligned it does not necessarily mean a company as a whole will be aligned or avoid citation if OSHA were to audit them. There is so much more that goes into collective company alignment with OSHA. For example, workers need to be observed applying in the field what they learned in the classroom. This observation/practical exam should be done by trainers, supervisors, or other designated competent persons. Whether you use our training kits or online courses, we provide guides to help employers do this. Other things that need to be done for ultimate alignment may include but are not limited to: addressing with your crew any gaps in the training or additional hazards or principles specific to your work situation; creating, training on, and enforcing and abiding by written safety programs (also known as plans or procedures); and performing regular inspections and risk assessments.

Are the e-learning classes up-to-date with OSHA standards?

Yes, all of our Hard Hat Training online courses are up-to-date with the latest OSHA standards. As standards change, we make changes to the courses. If you purchase any of our online courses outright, though, it will then be your responsibility to update the course in accordance with any changes to the standard.

Does this course certify or qualify me?

There is a lot of confusion among operators and even companies about what it means to be certified or qualified. Simply put, no, a course does not certify anyone, only an employer does. Or, in other words, because it is the employer’s responsibility to make sure an employee is properly trained, it is also his or her responsibility to say when the employee is “certified,” “qualified,” or “competent.” The online courses, like our training kits on CD or USB Drive or even live training via a 3rd party, is just a tool to help them in doing so.

According to OSHA, all operators of heavy equipment must receive operator training. Proper training must include a classroom portion including a written exam, as well as a practical hands-on portion/exam wherein the operator is observed operating the machine. The online course satisfies the required classroom portion of the training. Upon completion of the course and written exam, the safety administrator of the company will receive a checklist which can be used to observe the trainee on the machine. When done successfully, the administrator signs the bottom of the form. At this point, unless further training is required by your employer, you have done everything required by OSHA to be considered by your employer as “certified,” “qualified,” or “competent.”

If I pass this class and exam can I take my certification and get a job anywhere?

See “Does this course certify me?” This will depend on your employer. Remember, it is their responsibility to see that you are trained and if there is ever an accident, it is they who will have to prove to OSHA that they trained you sufficiently. Because of this, while some smaller businesses may simply accept your certificate and a copy of your test, more often than not they will require you to go through their own training program. This is their right to do so. It is their further responsibility to train you in accordance with the job, site, equipment, etc. Having said that, we have fielded many calls from potential employers who wanted to learn more about the classroom portion of the training we offered. After hearing our explanation, they accepted the online class as satisfying the classroom portion of the required training and proceeded to do their own practical.

How long is the training good for?

OSHA standards dictate that safety certification needs to be completed at least once every three years. Since no online course can provide “certification,” these courses will combine with your onsite practical training to fulfill OSHA’s requirements for up to three years. Having said that, refresher training is required sooner if an employee changes sites or jobs, is asked to operate a different type of the equipment, is involved in a near-miss or accident, or is observed operating the machine in a dangerous manner.

Will I get a certificate?

Yes, upon successful completion of the course and exam, you will have immediate electronic access to your test, a certificate, and a checklist you can use for the practical hands-on portion of the training. Simply print them off.

How many people can use this course? Can I play it for several employees at the same time?

When a course is assigned to an employee, only that employee can take the course. There are many reasons for this, but most importantly the course is designed to train that one employee per OSHA regulations. Also, there is a final written exam at the end that will be linked to the trainee assigned. OSHA requires proof of training and if multiple people were to sit in on that one course, they would not get credit for taking it.

Can I customize the classes?

Your business’s learning portal can be completely customized for your employees including colors and logo. Additionally, if you purchase our courses outright to be used on your own company LMS (learning management system), you also get the right to rebuild them and customize them to meet your own needs. If you have Adobe Captivate, which we use to build our courses, customization is even easier.

Are SCORM/Tin Can options available for use on our own company LMS?

All of our online courses are designed to be SCORM-compatible and can be easily uploaded to your company’s current SCORM-friendly LMS. You can license their use annually or purchase them outright. Licensing or purchasing them outright does not, however, give you the right to resell or distribute our courses to parties other than those whom you are training.

If we buy or license the eLearning courses for use on our own LMS, can you customize them for us?

Yes, we have done and continue to do this for clients. Pricing depends on the extent of customization requested. Please contact us for a quote.

Can I resell these trainings?

We do have resale options available. Contact us regarding resale opportunities.

How do I Look Up My OSHA Alignment Safety Certification?

So, you have already purchased a course from us, taken the online training, and passed the certifaction exam with flying colors. Now what? Most people want to print off a copy of thier OSHA Alignment Safety Certification and keep it for your records. Learn how to do that.
