QUESTION: ASBESTOS DEMOLITION

I'm seeking information concerning the requirements for heavy equipment operators working with Regulated Asbestos Containing Materials (RACM).

What is required when these individuals are working with asbestos; ie. demolition of structures containing RACM?

Your assistance will be greatly appreciated.

ANSWER:

I spoke with Wenqi "Sam" Sun, an asbestos expert. He says you are looking for "A Guide to Normal Demolition Practices Under the Asbestos NESHAP" by EPA.

QUESTION: ASP STUDY GUIDES

I am currently preparing to take my ASP examination. Do you have any suggestions on what the best study guides are for an adequate prep. I would also appreciate any information on preparation guides for the CSP. My ASP examination is 6 weeks out and I am utilizing the ASSE CSP study guide(4 volumes) but I dont feel I am preparing well enough with that alone. Any suggestions?

ANSWER:

I used the study guide from Las Vegas Workshop. Their toll free number is 888-589-6757. I was VERY pleased with their material for the ASP. I spent a few hours on weekends and then took an entire week to study their material - that was about IT. And I felt it was very good prep for the ASP. I also used their material plus another company's for the CSP. I thought Las Vegas was better for the CSP BUT no one really prepared me for the CSP. I was just glad I passed it and didn't have to try again. I've known a bunch of people that haven't passed those exams the first try, so if you don't pass at first, don't give up.

Also take a look at EPA's web page. At least scan through it so you have an idea about the terminology.

QUESTION: BLOODBORNE PATHOGEN WASTE

I belong to a safety committee and my company is working on proper disposal of bloodborne pathogen waste. I know that you must bag and tag all material that is considered blood from accidents (i.e. razor blade cuts, machine accidents, etc.).

1) What is the proper procedure for disposal? Who collects it, does the trash company?

2) Do sanitary pads from the ladies room have to be tagged as BIOHAZ waste?

ANSWER:

The best answers to most questions on the bloodborne pathogen standard can be found on the OSHA web page in the interpretations

OSHA's answer to sanitary napkins is:

"Q. Are feminine hygiene products considered regulated waste?

A. OSHA does not generally consider discarded feminine hygiene products, used to absorb menstrual flow, to fall within the definition of regulated waste. The intended function of products such as sanitary napkins is to absorb and contain blood. The absorbent material of which they are composed would, under most circumstances,prevent the release of liquid or semi-liquid blood or the flaking off of dried blood.

OSHA expects these products to be discarded into waste containers which are properly lined with plastic or wax paper bags. Such bags should protect the employees from physical contact with the contents.

At the same time, it is the employer's responsibility to determine the existence of regulated waste. This determination is not based on actual volume of blood, but rather on the potential to release blood, (e.g., when compacted in the waste container). If OSHA determines, on a case-by-case basis, that sufficient evidence of regulated waste exists, either through observation, (e.g., a pool of liquid in the bottom of a container, dried blood flaking off during handling), or based on employee interviews, citations may be issued." (end OSHA interp)

How you handle contaminated materials is another question. It depends on if the material is reusable (e.g. tools, machinery, knives, saws, clothing) or if it is disposable. It also depends on if the object is "saturated" on not. For cleanup of machinery & floors after an accident, may want to use a 10% solution of bleach or another "approved" disinfectant. Clothing and other PPE can be laundered but who does it and the procedures need to be clear. Disposable sharps are "usually" collected by a biohazardous waste company for a fee and incinerated. Although there are some other methods which encapsulate the sharps and render them harmless. Red bags of disposable materials other than sharps are often incinerated too, but there are other methods of effectively sterilizing these materials.

How you handle infectious material is usually regulated by your local health department. If you give them a call, they can direct you towards some good methods.

QUESTION: CIH STUDY BOOK

I enjoyed your math class at the Fl H+S conference. Please email me the name of the cih book you told me about at your mathematics class yesterday for preparation for the cih exam. Also let me know if there is some place that I can purchase the book for a reasonable price. I am interested in any other materials you could direct me to that help me prepare for the cih exam.

ANSWER:

The name of the book is "Quantitative Industrial Hygiene: A Formula Book" by Jack Caravanos available from ACGIH publication #3260 for $37. (It may be more if you aren't a member. Phone # 513-742-2020 I looked for a used copy but couldn't find one. I think this one is worth the money.

Jeff Burton's book that is used with the "Fundamentals of Industrial Hygiene" is also a very good book to study.

QUESTION: COMPRESSED GAS TRAINING

I would like relevant information on compressed gas safety training with the following topics;
1. General awareness
2. Emergency Response/procedure

ANSWER:

You need to read the OSHA standards in 29 CFR (Code of Federal Regulations) 1910.101 for compressed gasses. If you are doing welding, cutting or brazing, you will need to read that section too. If you don't have a copy they are available on the OSHA web page at http:www.osha.gov. Or you can get to it at:
http://www.osha-slc.gov/OshStd_data/1910_0101.html

Also, there are some very good instructions at the below web page: http://www.pp.okstate.edu/ehs/hazmat/labman/chapt2b.htm

If you need more advanced assistance you should contact the Compressed Gas Association.

QUESTION: CONCRETE FINISHER

Hello.

My husband is a concrete finisher..Last year he developed alkali burns from the cement...He has always soaked the burned area in peroxide, then covered the area with an antibiotic ointment (over the counter), he then places sterile bandages on the site, and wraps that with bandades to hold the bandage in place, so that he can work. We saw our family Dr. last year for this, and he said what he was doing was fine.

Recently my husband has developed these burns again.....Using the same treatment.....There is one burn on one finger, that has eaten away most of the layers of skin, to the first knuckle..It is beet red and oozing with infection..... Yesterday there are starts of the alkali burn starting on his other hand, affecting three fingers...

My question to you, is there anything else we should or could be doing.....to treat this and to prevent it...

ANSWER:

Your husband's burns sound like he needs more than first aid is needed. He probably needs to see a dermatologist. Also, try to get him to wear gloves or a barrier cream. Concrete, as you know, can inflict nasty alkali burns. If he works for someone else, the treatment of these burns should be covered by workers' comp.

Below are excerpts from a Material Safety Data Sheet for Portland cement. This information is supposed to be taught to each employee exposed to this type of hazard. The sheet with the hazard information (MSDS) is supposed to be provided by the supplier or manufacturer to each employer on request.

PORTLAND CEMENT

Toxicological Properties: The hazardous ingredients, when in contact with water, produce calcium hydroxide, with an alkalinity level of pH 12 to pH 13. This level of alkalinity can cause skin and eye irritation.

Route of entry: skin contact, eye contact, inhalation, ingestion.

Effects of acute exposure: Cement and wet cement mixtures can dry skin, cause alkali burns, and irritate the eyes and upper respiratory tract. Ingestion can cause irritation of the throat.

Effects of chronic exposure: Cement dust can cause inflammation of the tissue lining of the interior of the nose, and the cornea (white) of the eye. Hypersensitive people may develop allergic dermatitis.

Personal Protective Equipment:

Engineering controls: Ventilation should be sufficient in volume and distribution to maintain dust exposure below the TWA (10 mg/m3).

Spill or release: Remove by dry clean-up methods, which minimize the dispersion of dust. Avoid breathing the dust.

QUESTION: CONSTRUCTION, SHORTS

I CAN NOT FIND ANY REGULATIONS THAT STATE WHETHER IT IS LEGAL OR NOT TO WHERE SHORTS WHILE YOU ARE WORKING ON BUILDING CONSTRUCTION SUCH AS FRAMING AND FINISH WORK.

COULD YOU PLEASE HELP ME.

ANSWER:

I was not able to find anything in the "standards" that specifically says long pants are required on construction sites. However, the employer must assess the hazards and make work rules to protect the employees and these rules may include certain dress requirements.

There is an OSHA letter of interpretation dated 04/17/1997 on "Citations for the wearing of short pants by employees engaged in hot tar and asphalt construction work." This letter is located at:
http://www.osha-slc.gov/OshDoc/Interp_data/I19970417A.html

This letter includes the following instructions to OSHA Regional Administrators.

"Other factors may exist, however, which would pose a greater safety or health hazard than that of being burned by hot tar or asphalt. In such cases a citation of the PPE standard for lack of skin protection may not be appropriate. Naturally, workers at the site who are not exposed to the hazard of hot tar or asphalt coming into contact with their skin would not be required by the regulation to wear any kind of PPE intended to provide protection against that danger. To ensure consistency in the future application of 1926.95(a), compliance officers shall be instructed to carefully balance the need for personal protective clothing, such as long pants, during hot tar and asphalt operations against the need for clothing that is appropriate for severe environmental conditions such as extremely warm weather. "

I hope this helps,
Cynthia

QUESTION: DRY ICE

I'm a medical courier and I carry about 20 pounds of dry ice in my vehicle. I drive about 300 miles and am in the vehicle for an extended period of time. Is there any health effects from breathing the co2 from the dry ice evaporating inside the car. I frequently open the window to get some air inside. I get headaches often while driving but I think it maybe my vision, going for an exam tomorrow.

ANSWER:

Yes, there can be serious health effects from carbon dioxide. Carrying dry ice in a closed vehicle for long periods of time could result in exposure to high levels of carbon dioxide.

In itself, carbon dioxide is not considered to be highly toxic. However, one of the greatest risks is that it can displace the air in a closed system which will result in oxygen deficiency. Lower oxygen will cause you to loose coordination and mental abilities which are critical when driving a vehicle.

Making a few assumptions, if 1 pound of dry ice evaporated in a vehicle (5 cubic meters volume) with no loss from ventilation, it would result in a carbon dioxide level over 48,000 ppm. This is considerably higher than the OSHA permissible exposure limit of 5000 ppm averaged over 8 hours and nearly at the 50,000 ppm that NIOSH considers "immediately dangerous to life and health".

If you are employed by a company, I suggest you ask to see the Material Safety Data Sheet for the dry ice you carry. I also suggest you ask the company to assess the level of carbon dioxide you are exposed to during your travels. If the company would like some free assistance, they can contact the state agency in your area that provides FREE SAFETY & HEALTH CONSULTATIONS. To find the agency nearest you, go to the Consultation Project Directory http://www.osha.gov/oshdir/consul.html on the internet or you can call the local OSHA office for the telephone number.

For your information, I've included some excerpts of a material safety data sheet for carbon dioxide.

QUESTION: FORKLIFT INSPECTIONS

I have a conflict. As I read the OSHA requirements for forklift inspections, I do not find that a "written" inspection document is required. Will OSHA accept as verification, the fact that the Safety & Health Manual has written procedures and if they note, during the walk through, that employees are examining forklifts prior to use? Thank you for your help.

ANSWER:

My understanding is that if OSHA observes that good safety practices are in place, there is no written requirement now. If you are applying for ISO 9000 or others you may find that written verification will be required for that. So you know what to look for, I sometimes find the following problems when I observe forklift operations:
