HOTZONE IDENTIFIER HAZARDS
The Hotzone Identifier Hazards enables rapid identification of the hazard(s) associated with gas, solid, and liquid unknowns, spills, waste. This information is critical for the hazmat responders to complete the risk assessment. Categorisation of the potentially hazardous waste provides for its labeling, safe transport and disposal. The kit is self-contained and features the step-by-step field guide detailing the procedures which are quick and easy to perform.

Hotzone Identifier Hazards procedures use strip tests and wet chemistry tests to provide the user with the critical information on the unknown substances flammability, explosive behaviour, acidbase properties, aggressive/corrosive behavior, reactivity with water, oxidiser properties, potential toxicity, relative solubility and density. The kit also enables quick and simple identification of 5 most frequently encountered toxic industrial gases. The reagents, test strips and utensils are housed in the waterproof Peli-case in sufficient quantities to last for a relatively large number of tests. The built-in working surface provides for clean and convenient field work.

The first responders and the chemical waste managers need to know of the hazards related to the substances they are dealing with. Is there a fire or explosion hazard? Should water be used? Should runoff be contained? How to transport, label, and dispose of the waste? On the spot identification of the substances and materials may be complicated due to complex nature of the samples or event. Offsite laboratory analysis is often time consuming and relatively expensive.

Hotzone Identifier Hazards procedures aim to identify the hazards rather than the substance(s). That way they supply the user with the critical information needed to make expedient and safe decisions.

The test procedures are based on fundamental chemistry principles and thus reliable. However, they are simple enough to be performed by a nonchemist. The portable “laboratory” is housed in the customised PelicanTM case: corrosion-resistant, water-tight, shock absorbing, but still convenient to carry or store. The Hotzone Identifier HazCat kit ideally complements portable, handheld Raman technology such is the Serstech Indicator (http:// serstech.com/). Raman technology is the first choice for the responders on the field. However, this technology has its limits, notably when dealing with the thermally sensitive, complex, black and brightly coloured materials. The Hotzone Identifier Hazards allows for rapid assessment of thermal hazard of the materials and characterisation of the samples not amenable to the Raman.

HOTZONE IDENTIFIER EXPLOSIVES
The Hotzone Identifier Explosives enables rapid assessment and identification of explosives and their precursors. Easy to use, rugged and reliable tools provide the user with information on homogeneity, sensitivity to impact and flammability of the tested materials. The number of specific and generic analytical assays identifies commercial, military and homemade explosives (HME) and components. The kit is self-contained and features the stepby- step field guide in color.

The Hotzone Identifier Explosives features a set of tools and procedures to provide its user with the critical information on the unknown substances flammability, explosive behavior, acidbase properties, aggressive/corrosive behavior, reactivity with water, relative solubility and density. Wet and strip tests
detect explosive fuel precursors such as hydrocarbons, carbohydrates, heavy metals, sulphur and phosphorus. Oxidiser tests identify species known to be used with the explosive mixtures. Specific analytical assays target ammonium nitrate based explosives (ANAL, ANFO, ANS), PETN, RDX, TNT, Semtex, C3, C4, HMX, urea nitrate, chlorates, and azides.

Responders faced with an apparent, but not entirely characterised explosive threat have several options to consider. Waiting on the scene increases risk and delays decision making, therefore a fast action is the prerequisite. “Blow in place” practice with unknown chemicals could bring safety issues, bad public relations and it destroys the forensic evidence. Identifying the explosive components means understanding the threat, retaining the evidence and assuming the operations. On the spot analysis is preferable, since collection and transport of samples for the off-site identification is time consuming. Portable Raman and FTIR chemical analysis devices have caused a paradigm shift in field identification tactics. However, both technologies have limits and their use on unknown, potentially explosive materials bears safety concerns. The Raman technology commonly utilises a 785 nm laser, which can heat and eventually ignite some energetic materials. FTIR may require pressing of a powder sample to the sensor. A number of primary explosives are shock sensitive and easily detonate under pressure.
The sample may be a complex mixture containing heavy metal powders, hydrocarbons, carbohydrates, plastic binders and plasticisers, all interfering with the Raman and FTIR identification. The Hotzone Identifier Explosives ideally complements both technologies as it allows for rapid assessment of shock sensitivity and thermal hazard of the materials, providing safety protocols to the operators. The specific analytic assays enable quick identification of the explosives not amenable to the Raman and FTIR. All tools from the Explosives kit are carefully selected to be used with the potentially sensitive materials. The kit is self-contained with the reagents, test strips and utensils provided in sufficient quantities to last for relatively large number of tests.
