SKC D-TAM Skin Cleanser Developing Solution for Aromatic Amines

Introduction to Skin and Surface Sampling

Many occupational health professionals concentrate on air and particulate exposures in the workplace. However, NIOSH estimates that more than 13 million workers in the United States are exposed to chemicals that can be absorbed through the skin including production chemicals, disinfectants or cytotoxic drugs. To ensure a comprehensive worker exposure assessment, surface and dermal sampling need to be investigated as part of the assessment strategy.
This guide is intended to introduce a newcomer to SKC products that will enable the detection of chemicals that cause dermatitis or skin damage that can enter the body through intact skin and cause toxic effects in various organ systems.
The properties of such hazards that may penetrate or injure the skin, are also toxic if ingested and/or inhaled and can remain as a hazard on surfaces for long periods of time.

Contamination is very easy to pick up from things like lockers, surfaces in the changing room or at the place of work even before gloves are put on. Careful attention should be paid to areas not normally regarded as potential problems, for example safety glasses, which have good skin contact over the bridge of the nose and behind the ears. Both of these areas have soft skin rarely exposed to harsh treatment and are very good at absorbing chemicals.
Most permeability tests carried out on clothing do not take in to consideration any mechanical abrasion and its effect on reducing protection. If skin is contaminated before protective clothing is put on, the uptake into the skin after donning protective clothing can increase dramatically.
Once the inside, or contact surface of the clothing is contaminated it should be replaced immediately.

Suggested Workplace Procedure

INITIAL EXPOSURE SURVEY

• Determine areas and jobs where hazardous chemicals are used.
• Check work surfaces, tools, production equipment, chemical storage and transfer areas with SWYPEs, to verify the need for Personal Protection Equipment (PPE) for employees. Identify and mark regulated areas, tools, carts, etc.
• After establishment of regulated areas where potential for skin exposure exists due to work practices and job requirements, survey areas outside of these regulated areas where contamination may be transferred.

OBSERVE THE PROCESS OF FLOW

• Check the final form of any product from the regulated area to stop transference to other areas.
• Check equipment (paperwork, tools, transport vehicles, etc.) leaving the regulated areas to verify they are free of contamination.
• Decontaminate all materials with decontamination solutions before leaving the regulated areas.
• Mark with tags or special paint all tools, carts, etc. that can become re-contaminated during normal use. Tagging can signify the potential for contamination and possible need for PPE

SECONDARY EXPOSURE SOURCES

• Observe the flow of people entering and leaving the regulated areas.

• Check water fountains, telephones, washing and changing rooms, lockers, and eating areas with SWYPEs. This will show contamination transferred via workers hands, clothing or shoes.

• Check office floors and aisles leading out of regulated areas, doors and door handles, office equipment such as phones, desk top computer keyboards even pens and pencils.
  Any of these items may have been contacted by contaminated PPE, clothing or shoes.

• Check and decontaminate all safety glasses, respirators, gloves and reusable personal safety equipment that are used in the regulated area.
  Replace any equipment that cannot be thoroughly decontaminated.

• Check surfaces, tools, measuring equipment in the QC labs that may carry contamination around the factory during or after quality checks.

THE ONGOING PROGRAMME
Weekly surveys will determine the need for decontamination and reinforce employee awareness.
Changes in process, chemical usage, PPE supplier, batch to batch variations and ongoing training requirements require thorough re-evaluation of hazard assessment.
A frequent programme of assessment and decontamination will yield best results in minimizing exposure hazards.

Colormetric Surface SWYPEsTM

Chemical contamination on workplace surfaces can result in significant skin exposure. Identification of areas and tasks for risk of dermal exposure is a critical element in a hazard assessment as required by OSHA’s PPE standard.
SWYPEsTM are a simple and sensitive technique to identify contaminated work sites where protective gloves and clothing must be worn.
Pump seals and hose connectors can be checked for leaks with Surface SWYPEs. Skin contact with uncured materials or surfaces in contact with uncured materials may result in worker exposures.
Procedures for the handling of drums should be checked to ensure that drum surfaces do not become contaminated.
Surface SWYPEs can also be used to determine that urethane parts are completely cured before being handled with bare hands.

Gloves should be worn when using the Surface SWYPE detectors.

1. First, lightly spray the area to be tested with Developing Solution.
2. Wait approximately 30 seconds and then wipe with a Surface SWYPE pad.
3. Allow 2 – 3 minutes for the colour change reaction to occur.
4. Do not reuse the Surface SWYPE after activation.

The sensitivity of the Surface SWYPE is 3-5 µg for aromatic amines and isocyanates.

Colormetric Skin SWYPEs

A common sense approach is the key to the successful use of the SWYPE detection systems for reducing workplace exposures. The first step is to observe employee work practices.
Tools, machinery controls, safety glasses or pencils that are handled with contaminated gloves, and may later be touched by bare skin, represent potential exposures.
The rapid colour indication of the Skin SWYPE helps to reinforce safe work practices and to educate workers in the prevention of skin exposures. They can also be used to test employees’ hands to verify that gloves are providing protection from exposure.

Using Colormetric Skin SWYPEs

1. Using moderate pressure, wipe the suspected exposed skin area (behind the ear, pencil; bridge of nose, safety glasses, etc.) with the cloth pad portion of the Skin SWYPE.
2. Use a separate SWYPE for each area to be checked. To process, add 6 mm of Developing Solution to the small plastic cup provided. Place the Skin SWYPE in the cup with the cloth pad portion in the solution and the colour detection strip up at the top. The solution will cause a wicking process, carrying any contaminant, to the detector pad.
3. Remove the SWYPE from solution cup when the detector pad is saturated.
4. The test takes a minimum of 5 minutes for the colour change reaction to occur.

Wipe skin with SWYPE

Developing and Cleaning Solutions

The Cleaning/Developing Solution is necessary in order to increase the sampling efficiency of both the Surface and Skin SWYPE detection systems.

• When testing for contamination, the surface is lightly sprayed with the Cleaning/Developing Solution.
• The solution dissolves the contaminant prior to using the Surface or Skin SWYPE™.
• The SWYPE is designed to wick the solution into the pad, increasing the detection level, particularly on rough or porous surfaces.

DECONtamination Solutions are an important element in a dermal exposure reduction program.

A regular program using SWYPE detection followed by decontamination will assure minimal dermal exposures.

Cleaning/Decontamination

1. Wet area thoroughly with Cleaning/Developing Solution for Aromatic Amines

2. Use an abrasive pad if necessary, to enhance penetration. Do not rinse
   before applying Decontamination solution.

3. Spray the area with Decontamination solution and allow it to react for at least 5 minutes. Rinse with water.

4. Recheck the area with Surface SWYPE to verify decontamination is
   complete. If contamination is still present, repeat steps.

5. To decontaminate tools, mix 1-part DECONtamination solution with 3 parts
   cleaning/developing solution in a closed container.

6. Let tools soak for a minimum of 5 minutes and rinse with water.

7. Recheck with Surface SWYPE to verify decontamination is complete.

PERMEA-TEC Pads – Breakthrough Indicators for Gloves

Gloves and other personal protective equipment (PPE) can be evaluated for effectiveness in actual field use conditions with PERMEA-TEC Pads.
PERMEA-TEC Pads include both direct-reading colorimetric detectors and a micro-encapsulated solvent indicator system.
Chemical penetration through PPE is indicated by the pads changing colour. Normal sensitivity range, from 0.5 to 5 mg.
Indication of breakthrough can greatly improve PPE selection for specific applications.
To determine a user-safe time period for the glove, double gloving is recommended.

Steps :

1. Affix PERMEA-TEC sensors to the thumb, middle finger, and palm on the outside of the glove
   currently being worn and then place the glove to be evaluated over the first glove.

2. After one hour, remove the outside glove and the underlying PERMEA-TEC sensors.

3. Develop the pad by spraying it twice with Aromatic Amine Cleaning/Developing Solution.

Interpretation of results

1. A positive indication of breakthrough results in a colour change.

2. If no breakthrough is indicated, apply fresh PERMEA-TEC sensors and continue to wear the outside glove for another hour. Follow the steps above to determine if breakthrough has occurred
   and to determine a user-safe time period for gloves.

3. Send PERMEA-TEC Pads to a laboratory for analysis to identify the chemical, solvent or other
   compound, penetrating the gloves or garment.

SKC Full Disclosure® Kit

KC Full Disclosure® wipe sampling provides instant detection of lead on skin and surfaces.

• Completely safe surface and skin testing
• Immediate colour change
• Easy to use
• Developed, tested and patented by NIOSH, CDC
• Meets NIOSH Method 9105 for Lead in Dust Wipes

Applications

• Identifying presence of lead and confirming decontamination by retesting
• Ensuring effectiveness of hand and skin washing for individuals exposed to lead (e.g. shooting ranges)
• Determining the effectiveness of lead removal

How It Works:
The test surface, i.e. skin, safety glasses, tables, workbenches, shoes, etc. is wiped with a wipe to collect lead that may be present. The mildly acidic aqueous solution is then sprayed onto the wipe to solubilize the lead, and then the aqueous rhodizonate test reagent is sprayed onto the wipe to produce the results. If solubilised lead is present, a pink to red colour bloom will appear immediately. The intensity of the colour bloom can indicate the relative amount of lead present. Positive wipes can be sent to a laboratory for quantitative analysis if desired.

Step 1 Prepare the solution

Step 2 Wipe to sample

Step 3 Spray and read the results
