Garbage Bags – Low Density Polyethelyne
LOW DENSITY LINER
Low Density liners are the ideal choice for applications which require significant material flexibility, in addition to strength and durability. Berry’s low density liners have the ability to elongate under stress, allowing them to maintain without puncturing, tearing, or cracking. Combined with outstanding resistance to low temperatures and ultraviolet exposure, these liners are ideal for many applications Puncture Resistance – High puncture strength
- Flexibility – In addition to UV and chemical resistance, Low Density Liners exhibit a high degree of flexibility. Greater flexibility provides increased conformance to subsidence and settlement.
- Low Density liners are lower cost and suited for applications where trash is high bulk and low weight.
- A good rule of thumb it’s a back building liner, holding metal, wood, nails, cans anything that’s sharp that could puncture a bag.
Garbage Bags – High Density Polyethelyne
HIGH DENSITY LINER
From small office wastebaskets to large outdoor trash bins, high-density bags have the strength and capacity to accommodate trash containers of all sizes in establishments.
- High-Density Liners are up to three times stronger, and weigh half as much as low density liners. Substantial material savings on a per liner basis.
- Are an excellent economical choice for heavy, wet trash and soft refuse, not suitable for trash with sharp edges or sharp points
- Offer superior vapor and moisture protection.
- Have smaller, lighter cases, which lower freight costs, storage and warehouse costs
- High Density Liners (grocery bag material) punctures, with a zipper quick reaction
- Are more temperature resistant than low density liners
- High Density liners, a good rule of thumb it’s a front building liner (holding smooth and heavy material)
- Greener choice as they hold more trash per pound which requires less plastic waste
Protective Apparel
Safety Supplies Michigan
Hazardous & Non-Hazardous Protective Apparel
There are a number of types of outer clothing including non-hazardous apparel (for use in oil, dirt and grime where the wearer does not want to get clothes soiled), and hazardous apparel, including toxic waste, fire retardant and chemical apparel.
The non-hazardous apparel is usually called “Limited Use and/or Disposable.” This type of clothing comes in a variety of styles. The wearer can have items by the piece; pants, jacket, sleeves, boots, apron, hood and full face hood and shield or he can wear One-Piece Coveralls that can come with elastic wrist/ankle bands for a tighter fit. The coveralls can come with boots, hoods and complete hood w/face shield.
Lakeland makes their disposable garments from two types of material, MicroMAX, which is general purpose protective material that can be used in any non-hazardous environment. MicroMAX is comprised of a microporous film with a nylon scrim between the film and the sub-strate, this gives the material added strength. The other material is “Tyvek”.
There are different types of MicroMAX clothing signified by the type of use, seam joints and composition. They are HBF, NS and NS Cool Suit.
HBF utilizes the fabric structure to limit challenge material penetration through the fabric. The same fabric structure, when combined with the physical properties of the melt-blown layer, promotes the exchange of air and moisture between the inside of the fabric and the exterior. The result is outstanding barrier and comfort. NS features high MVTR’s and is breathable for worker comfort. MicroMAX® NS is strong, wet or dry. NS Cool Suit is made with the same material with an added spunbond polypropylene back panel. This give the suit added breathability.
The different types of stitching used in the clothing are Serged Seams, Sewn and Bound Seams and Heat Sealed Seams. A serged seam joins two pieces of material with a thread that interlocks. This is an economical stitching method for general applications. It is more commonly found on limited use clothing where dry particles are of a concern.
A sewn and bound seam joins two pieces of material with an overlay of similar material and is chain stitched through all of the layers for a clean finished edge. This provides increased holdout of liquids and dry particulates.
A heat sealed seam is sewn and then sealed with a heat activated tape. This method provides liquid proof seams, and is especially useful for Level A and B chemical protective clothing.
The basic OSHA Standard calls for 4 levels of protection, A – D and it also specifies in detail the equipment and clothing required to protect the wearer. Lakeland makes Level A and Level B apparel.
Level A represents the greatest danger to respiratory, eye and/or skin damage from hazardous vapors, gases, particulates, sudden splash, immersion or contact with haz-mat. It calls for total Encapsulation in a vapor tight chemical suit with self contained breathing apparatus (SCBA) or supplied air.
Level B situations calls for the highest degree of respiratory protection but a lesser degree of skin protection. It calls for SCBA or positive pressure supplied air with escape SCBA. Level B suits can be fully encapsulated or pieced together in various garments.
Lakeland Industries is a licensed manufacturer of quality Tyvek® Protective Wear™ products. Lakeland is a registered company manufacturing to ISO 9001 specifications. Additionally, our Tyvek® Protective Wear™ meets or exceeds ANSI 101-1996 sizing requirements, and are required to pass dynamic fit tests to minimize rips and tears. All Tyvek® Protective Wear™ garments are clearly marked with a blue label to distinguish them from others which may have not been manufactured from Tyvek® or under the entire quality system. It’s your assurance of quality manufacturing that strengthens your safety combination.
Gloves Chemical Protection
Safety Products Michigan
To detemine which glove is best suited to protect against any given chemical the following test are conducted.
Glove Permeation Testing
Permeation testing is goverened by ASTM Method F739 standards. A specimen membrane is cut from the glove and clamped accross a test cell as a barrier. One side of the barrier is exposed to a hazardous chemical. In intervals, the unexposed side of the test cell is checked for evidence of the permeated hazardous chemical. The extent to which it may have permeated the glove material is also measured.
This standard allows a variety of options in analytical technique and collection media. Dry nitrogen is the most common medium and gas chromatography with FID detection is the most common analytical technique. The most common collecting media liquids are distilled water and hexane, and techniques such as conductivity, colorimetry, and liquid chromatography for analysis of the collecting liquid.
Glove Degradation Testing
The glove material is stretch accross a vessel. The glove material barrier is weighed and measured. It is then completely immersed in the test chemical for 30 minutes. Key measurements are the percentage of change in size, and the percentage of weight change. The material is dried to determine weight change. Observed physical changes are also reported and a ratings is given based on the combined data.
