Global Classification Systems for Chemical Protective Apparel

ISO 16602 and ANSI/ISEA 103 provide a way for you to specify its performance in an objective and detailed manner. When faced with protecting workers from chemical hazards, there are no "all hazards" chemical protective garments. The chemical hazard, work activities, and environment vary from job to job. An "all hazards" garment would end up being too protective in most situations. Over-protection may limit the workers' ability to perform their jobs, adds the risk of heat stress, limits the workers' ability to see or be seen, reduces agility and dexterity, and adds cost. That is why you have so many chemical protective clothing options available to you. The task becomes selecting the garment with the right seam, design, and material and selecting the matching respirators, gloves, and footwear. And that selection process must also consider factors such as flex and abrasion performance, cut resistance, flame resistance, and color.

You now have access to three chemical protective clothing classification systems that consider most of the important factors. When fully adopted, these classification systems will help you select chemical protective clothing for your situation...One system is found in the recently released American National Standard for Classification and Performance Requirements for Chemical Protective Clothing (ANSI/ISEA 103). The second system is found in ISO 16602 Protective clothing for protection against chemicals -- Classification, labeling and performance requirements. The ISO system closely resembles the oldest six-level classification system developed by the Committee for European Normalization (CEN).

Is Grip the New Safety Feature?

Grip is indeed the new safety feature. But why is grip able to offer the glove user more safety? The answer to that question is yes: Grip is indeed the new safety feature. But why is grip able to offer the glove user more safety? Surely gloves have always had grip, so how can this be a new thing...

Vulnerability of oil contaminated fire retardant overalls

Overalls become oil-contaminated very rapidly in many work situations, particularly offshore, in some cases within one day. From time to time, there are significant hydrocarbon fires offshore. There is evidence that frequent washing reduces the fire retardant properties of some materials, thereby increasing personal risk to persons and compromising their safety in a fire. Secondly, there is a problem with fires in the laundries offshore. Because of the large potential for escalation of fires offshore, the reduction of fuel loading and the prevention of ignition sources must remain a high priority. The presence of possibly flammable, oil-contaminated overalls with potential for self-heating exacerbates this problem. Therefore, an experimental trial has been commissioned to investigate the possible degradation of the fire performance of fire protective overalls. This began with, a review of national standards to identify a suitable measure of fire performance that can be used to measure possible loss of protection after laundering. This in turn was used to establish a test procedure to allow the comparison of new fire retardant material with laundered material, both stained and clean.

Survey: PPE Noncompliance Poses a Serious Threat to Worker Safety

Employees who believe PPE is not necessary for their work or who consider it too uncomfortable to wear run the risk of leaving themselves unprotected and vulnerable to occupational injuries. According to a new survey from Kimberly-Clark Professional, this happens all too often.

Outil d'estimation de la durée d'utilisation d'un adsorbant



Outil d'estimation de la durée d'utilisation d'un adsorbant

 MARSTEAU S., et coll.

L'estimation de la durée de vie des média utilisés pour épurer un air pollué est une question fréquemment posée dont la réponse est rarement aisée, notamment pour le domaine des appareils de protection respiratoire (APR).
Un outil de calcul informatique a été développé à partir d'un modèle empirique reconnu, basé sur l'équation de Wheeler-Jonas et d'un certain nombre d'essais réalisés à partir de bancs de génération d'atmosphères polluées. Cet outil permet à un utilisateur d'estimer la durée de vie des cartouches de son APR à partir de données d'exposition : type de polluant(s), concentration, température, débit respiratoire, type de cartouche(s), etc.
Cet article décrit le modèle développé et présente quelques résultats expérimentaux de validation ainsi que des perspectives d'évolution de l'outil.
