Technical Bulletin List

A series of internal bulletins focusing on technical developments, safety practices, and innovation topics across the industry.

All types of detonators, despite advancements in their design and manufacturing, require careful handling. Always
follow the manufacturer's instructions, as they remain vulnerable to accidental activation caused by impact, heat,
or friction.

This document outlines the primary causes of flyrock, which refers to rock being uncontrollably projected during a
blast, and provides recommendations to help reduce the risks and prevent such incidents.

Explosives nearing the end of their shelf life or showing deterioration must be carefully examined to ensure they
are either safe for use or transport for destruction. Recognizing signs of deterioration is crucial to avoid accidental
detonation or misfires due to changes in sensitivity.

Misfires carry significant risks, emphasizing prevention over reaction. Handling misfires is highly hazardous, as
unexploded charges or detonators may remain in the blast area or debris, posing danger if struck or transported.
Such circumstances risk harm to operators and the public, especially through flyrock from unexpected
detonations. Recovering unexploded charges requires meticulous care to ensure safety.

This bulletin addresses short-term desensitization of explosives sensitized with either gassing agents or
microspheres used in mining and construction. Initiating explosives during reduced sensitivity may result in poor
blast performance, adverse fumes, combustion, or misfires. Two types of short-term desensitization are identified:
Shock Desensitization and Gas Pressure Desensitization.

Loading ANFO can pose hazards due to the accumulation of electrical energy at various points in the process. A
semi-conductive path to ground must be ensured to safely dissipate static electricity and prevent dangerous
energy build-up. Using a well-maintained semi-conductive loading hose is critical, as it must (1) dissipate static
electricity safely and (2) resist stray currents from reaching detonators. Pneumatic loading systems should include
properly grounded equipment and suitable hoses. Additionally, detonator leg wires should be shunted during
loading to reduce risks.

While the risk of premature detonation due to radio-frequency radiation is very low, it can still occur under certain
conditions. Hidden sources of radio-frequency energy, both within and outside the blasting site, such as radio
equipment from vehicles or visitors, or distant transmitting aerials, may increase the hazard. Electronic detonators
also carry the risk of communication interference between the exploder and detonator.

This Technical Bulletin is intended to provide information to members of the public living close to blasting
operations regarding the environmental impact of blast-induced ground vibration and air overpressure.

The detonation of explosives primarily produces Carbon Dioxide, Nitrogen, and Water Vapor (steam). However, it
can also generate toxic gases such as Carbon Monoxide, Nitrogen Monoxide, Nitrogen Dioxide (collectively
known as NOx), and Ammonia.

Spent Acids in NG production can separate and accumulate dangerously, leading to serious accidents. This Note
offers industry guidance on handling Spent Acids and effluents safely. Explosives, composed of oxidizers and
fuels, may pose environmental risks if misused. Pollution must be prevented or minimized, considering technical
and economic limitations. This bulletin provides general advice on mitigating these environmental effects.

Blasting in quarries and surface mining involves various hazards beyond handling detonators and explosives.
One significant risk, for instance, is working near crests, which increases the likelihood of falls. This guidance
aims to promote safer practices in quarry operations.

The standard work operation procedure describes the steps in loading a blast with bulk explosives. The
procedure covers pre-loading, loading, stemming, connecting, blast firing and post blast inspection steps for blast
loading with bulk explosives.

The purpose of this technical bulletin is to provide safety advice on how to proceed in the event of a fire in a
vehicle carrying explosives, detonators and / or oxidizing agents. This technical bulletin covers fires on vehicles
carrying explosives and/or Oxidizers. The term Oxidizer refers to Ammonium Nitrate and mixtures that contain
Ammonium Nitrate.

Guidance Notes List

Comprehensive guidance documents developed by Working Groups to help members navigate key regulatory and operational challenges.

This document describes the hazards, the acceptable levels of exposure, and the protective practices that are to
be observed when employees may be exposed to NG or EGDN.

This documents outlines the hazards, acceptable exposure limits, and protective measures to safeguard
employees when exposed to DNT and its products. It also includes existing studies on the health impacts of DNT
exposure.

Blasting activities generate ground vibrations, that are dispersed as seismic waves. This document is focused on
the understanding of the generation, propagation and mitigation of such waves by the users of explosives.

This documents outlines the hazards, acceptable exposure levels, and protective measures to safeguard
employees when exposed to TNT and its products. It also includes existing studies on the health impacts of TNT
exposure.

Definition of protective measures when using chemical substances in the explosives industry that may pose
physical, biological, biochemical, and ergonomic hazards.

This Guide provides recommended practices for training staff, drafting and revising operating instructions, and
advising new operations without prior experience, offers broad guidelines for creating tailored instructions,
serving as a checklist to evaluate both new and existing manufacturing control systems.

While proposing international adoption of best practices for distribution of explosives, explosives precursors and
accessories, the proposed Note is estimated to address only a small percentage of materials used in such
activities.

This document outlines widely accepted guidelines for the storage of explosives and accessories. While it
primarily focuses on permanent magazines holding more than one tone of explosives, its principles based on
current best practices, can be applied to all storage operations.

Spent Acids in NG production, as NG can separate and accumulate dangerously over time can provoke serious
accidents. This Note provides guidance on handling Spent Acids and effluents based on industry expertise.

The shelf life of explosives, accessories, and devices is heavily influenced by their composition and construction.
When these products are stored under optimal and controlled conditions, the product groups outlined in this Code
will function reliably.

This Note provides advice on safe disposal methods, necessary precautions, and practices to avoid. It is intended
for trained engineers and technologists dealing with large quantities of surplus explosives, complementing
guidance for smaller amounts.

Under controlled good storage conditions, the product groups listed in this Code will perform satisfactorily
provided they are stored and used in accordance with the Federation Codes issued covering use, storage and
transport.

The recommendations contained in this Note give to the members of FEEM broad guidelines on which they can
devise an appropriate strategy for "CRISIS MANAGEMENT" and have been drawn up after in depth consultation
with experts within the industry and those skilled in the management of crisis and therefore, represent the best
possible advice in current terms.

This Note outlines the basic requirements for the shotfirers courses to cover the general and specialist fields of
use.

The guidelines focus on safety measures for plant layout and building design, aiming to minimize the impact of
accidental explosions and safeguard workers. These recommendations, address precautions to optimize safety
and consider factors like factory layout, distances, and quantities of explosives in process.

With the newer technology of waterbased explosives this hazard pattern has been dramatically changed in that
the main hazard component, the explosive sensitiser, has been removed. With each explosive there is, however,
a point reached where a combination of such factors stress the safety tolerance of the explosive beyond its limits
which results in an unintentional initiation and accident. This "critical stress level" varies from explosive to
explosive but the factors involved are common to all.

This Note governs the basic safety principles to be observed in the manufacture, storage and handling of initiating
(primary) explosives and mixtures of such materials; it covers both process operating standards and engineering
standards applicable to process equipment and buildings used in initiating explosives manufacture.

FEEM has developed controlled blasting guidelines to enhance the safe use of explosives and optimize their
performance in underground operations. Adequate ventilation, is essential to manage exhaust gases effectively
and maintain safety standards.

The procedures outlined in this guidance note cover the destruction of small quantities only, up to 25 kg of
explosive in total or 50 detonators.

The destruction of explosives, whether by burning or detonating, typically requires approval from authorities.
Certain devices containing explosives in metal containers or parts, like shaped charges or explosive bolts, pose
specific risks related to shrapnel. Consequently, the destruction of such products should only proceed after
consulting the manufacturer to ensure safety.

In this Guide, the word "shotfirer" is used to designate any person who is responsible for designing as well as the
person who actually handles loads and fires explosives material. It should be noted that this definition of
"shotfirer" is rather wider than is normally the case, but the intention is to ensure that persons who have the
responsibility for supervising and designing blasts as well as persons who handle explosives are properly trained.

This Guide emphasizes responsible blasting practices, focusing on reducing or preventing ammonium nitrate from
dissolving in water to mitigate contamination risks. While it does not cover all aspects of effective blasting, it
highlights key considerations related to water pollution.

This Guide focuses primarily on chemical hazards from substances and preparations in the explosives industry, .
where employers must specify protective measures, with both employers and employees sharing responsibility for
implementation.

The classification of the non-sensitized emulsion matrix varies across Europe. If deemed non-explosive, it can be
transported in vehicles outside Class 1, though still subject to national regulations for hazardous chemicals.
However, if classified as Class I, it must comply with the relevant transport regulations.

transported in vehicles outside Class 1, though still subject to national regulations for hazardous chemicals.
However, if classified as Class I, it must comply with the relevant transport regulations.

The use of AN / FO mixtures has popularized on-site mixing, offering cost efficiency across various applications.
However, relocating explosive production from tightly regulated factory settings to less controlled environments
has introduced new challenges, so the purpose of this Guide is to endure that the practices with AN/FO mixtures
are of the highest standards.

This Guidance Note not only indicates the basic requirements of a shotfirer but also indicates the contents of
training courses and specifies detailed information and the degree of on-site training and experience which a
shotfirer should possess before his appointment.
