Chemicals, Gases, Materials Accidents
Work involving chemical exposure, with or without chemical explosion, generally covers:
Reconstruction of accidents involving chemicals, gases and hazardous materials determines whether such chemicals, gases and materials caused or contributed to an accident. Reconstruction of accidents involving failure of materials of construction determines whether the materials failed due to unsuitability in use under intended conditions or their use was outside of intended conditions of use, according to instructions, specifications, codes or standards. Work in this area also generally includes determining whether revision of packaging, containment, method of use and/or warnings and the instructions for use was required for safety. 
  • determining whether containment systems or packaging for chemicals and gases were: 
  • defective in design, manufacture or installation 
  • lacked adequate warnings
  • determining whether the manner that chemicals or gases were used was hazardous
  MAAFE
  • determining whether the hazardous use of the chemicals was due to: 
  • the instructions for use
  • deviation from the instructions for use
  • as a result of a lack of instructions for safe use 
  • household cleaning chemicals in plastic bottles
  • industrial and commercial cleaning chemicals in barrels
  • industrial and commercial cleaning chemicals used in cleaning equipment at the time of accident
  • uncured concrete (cement, aggregate and water) delivered pre-mixed by truck
  • dry cement, and dry concrete (cement and aggregate) in packaging for mixing with water
 MAAFE
  • fasteners and associated fastened materials (at each end of the fastener) used in various ways with various equipment and components, including industrial, commercial, and residential equipment and components
  • determining the chemicals involved in the explosion, when there is an explosion 
  •  MAAFE
  • determining if other chemicals were inadvertently involved

This makes chemicals with incomplete Warnings or Warnings which are erroneous to one degree or another, a particular hazard, particularly with chemicals sold outside industrial commerce. Chemicals sold outside industrial commerce can be very dangerous. These chemicals are sold to the general public for personal use and for use in their homes and gardens, to professionals who use them in their work activities, such as in cleaning, maintenance and construction, to farmers and to others for various uses. Chemicals sold to the general public, farmers, professionals and others outside industrial commerce include cleaning products, maintenance products (for example, pool chemicals), pesticides, herbicides, building materials, personal care products, etc. Many of these chemicals are dangerous, either when in contact with body parts and/or from violent interactions with other chemicals sold outside industrial commerce, as well as chemicals sold within industrial commerce. Warnings are extremely important for the safe use of chemicals and materials that contain chemicals.
Only very rarely is a chemical pure when sold in commerce. Essentially all chemical products are mixtures of chemicals, both chemicals desired to be in the mixture and chemicals which are too difficult or expensive to remove from the mixture. This is true of chemicals sold to the public and chemicals sold to professionals and industry. A particular concern with chemicals is that the exact hazard is usually cloaked in mystery until the exact composition of the chemical is known. From a practical standpoint this information can only come from the supplier of the chemical in the form of a Warning. 
Often the most important protection available is personal protective equipment. This is a form of safeguard. However, Warnings are required to inform the user as to when such protection is required and what specific protection is required. Warnings also must perform well in the areas of informing the user of the consequences of contact and chemical interactions, on how to avoid contact and chemical interactions, and what to do if they come into contact with chemicals.

            were: 
  • defective in design, manufacture or installation
  • were the proper materials for the use
  • lacked adequate warnings for their proper use to avoid creating a hazardous condition
  • determining whether the manner in which the materials were used created a hazardous condition

See the section below for discussion of Warnings for Chemicals and similar Hazardous Materials
See the section above for examples of Chemicals and Hazardous Materials analyzed
The use of Warnings with chemicals is regulated by legislation and codes and standards with requirements for providing significant safety information in prescribed forms. These requirements take into consideration the very restricted role that Safeguards can take in use of chemicals, thus putting the safety burden on Warnings, particularly for the public and professionals outside industrial commerce. This important safety role for Warnings is also true for similar hazardous materials which are hazardous at least partially because they contain chemicals. Other hazardous material which are primarily chemicals or in which chemicals are an important factor include such materials as concrete, (dry) cement and some wall board formulations. 
Our work includes engineering analysis of the containment or delivery method of the associated chemicals, gases and hazardous materials. Our work includes engineering analysis of materials of construction, and reconstruction of containment failure and material failure, including securement failure, when such has occurred. Our work includes assessment of the activities of persons involved in the accident, chemical delivery, and/or materials failure, particularly in regard to the handling of hazardous material and/or the failure of materials. Our work includes assessment of the use of safeguards and warnings, and their effectiveness, and assessment of the adherence to instructions for use and adherence to applicable codes, standards and recommended practices on the part of the user, manufacturer, supplier, etc.
Our Work with Chemicals, Gases, Materials, and Related Subjects and Issues -  is largely about the properties of chemicals, gases and materials and the consequences of these properties. Our work includes determination of the cause(s) of accidents associated with these materials, including issues with labeling, delivery and containment of chemicals and gases, and correct use of materials of construction (MOC), including with securement, such as fasteners. These accidents may include contact with chemicals, gases and other hazardous materials, such as uncured concrete, which results in injury, usually chemical burns or injury from inhalation. These accidents may include chemical explosions, often with household chemicals, resulting in injury or property damage. These accidents may involve failure of materials of construction, including containment materials and securement materials, such as fasteners. Insofar as failure of materials of construction is a factor in equipment or component failure, this work would overlap with our work with equipment and components as described elsewhere in this website.
