§ 1910.109 Explosives and blasting agents. (a) Definitions applicable to this section—(1) Blasting agent. Blasting agent—any material or mixture, consisting of a fuel and oxidizer, intended for blasting, not otherwise classified as an explosive and in which none of the ingredients are classified as an explosive, provided that the finished product, as mixed and packaged for use …
Guide to use of table of recommended separation distances of ammonium nitrate and blasting agents from explosives or blasting agents.
Quarry blasting is the controlled use of explosives to break rock into smaller, manageable pieces for extraction and processing in quarries. This technique is essential for efficiently accessing and removing materials such as stone, gravel, and other aggregates needed for construction and industrial applications.
Accordingly, the present invention provides a composition useful for quarry blasting and other excavation works which comprises an oxidizing agent selected from ammonium nitrate, sodium nitrate, calcium nitrate and potassium nitrate in the range of 85 to 95 wt %, reducing agent selected from coal powder/activated carbon and guar gum in the ...
Blast design should be a balancing act of getting the best fragmentation without creating unwanted impacts such as excessive vibration, airblast, flyrock or NOx. Using bulk emulsions as part of the blast design process is a smart way of managing these impacts.

manufacturers. OSHA's standard on Explosives and Blasting Agents, 29 CFR 1910.109, provides a definition of explosives and pyrotechnics. For a full compliance guide to PSM, please refer to OSHA 3132. 1. or the full text of the standard at 2. Although all elements of the PSM standard apply to a PSM ‑
neighbourhoods, blasting is a necessary step in extracting aggregate at quarries. To ensure blasting affects nearby communities as minimally as possible, provincial government regulations set limits for noise and vibration produced by blasting at Ontario quarries. Every blast that takes place is closely monitored to ensure that these limits are
Ammonium Nitrate is an adaptable oxidizer that works well when explosions are needed during mining or quarrying operations. When combined with fuel oil, it makes an effective explosive that has a wide range of applications. We offer a full range of packaged and bulk ANFO, including our DYNOMIX™, DYNOMIX™ WR and FRAGMAX® line of products.
Examples of fuels and sensitizers, as well as oxygen source, are: Blasting agent (BA) = a mixture consisting of a fuel and oxidizer, intended for blasting but otherwise not an explosive (cannot be detonated with a No. 8 blasting cap).

However, there are several oxidizers that could be considered as possible replacements for ammonium nitrate if needed. After a critical evaluation two possible alternatives are recommended for further study: the use of sodium nitrate as a partial replacement and the development of a new type of blasting agent based upon water as the main oxidizer.
Orica's range of solutions for wall control blasting enables steeper walls and faster vertical advance in cutbacks; reducing the stripping ratio, bringing forward revenue and increasing the project NPV. Consistently delivering high production rates enables a quarry to operate efficiently.
the blasting agents of this invention can be formed by mixing an aqueous solution of an inorganic oxidizing salt(s) alone or together with nitrogen-base salt with organic fuel containing a lipophilic emulsifier, agitating the mixture until a thickened emulsion is formed and then incorporating gas, by the addition of gas-carrying matetial e.g., microballons or injection of air, and obtaining a ...

Manufacturing Blasting Agents and Oxidizers. Nelson Brothers has been manufacturing our signature PowerNel™ emulsions for nearly four decades. PowerNel™ products are trusted across the industry due to consistency in our manufacturing process and the high-quality raw materials that go into our products. Nelson Brothers produces our own blend ...
A straight ammonium nitrate emulsion provides the greatest water resistance. But ANFO generally provides a better blasting result in quarry applications. This is where blends come in to play. A blend product is a mixture of ANFO and emulsion. When ANFO and emulsion are blended together, the emulsion coats the prills of …
A blasting agent is a substance or mixture made up of fuel and an oxidizer that is utilized for blasting purposes. It is not, however, classified as an explosive, as some of its ingredients are explosives. When confined, it should not be able to be detonated with a No.8 blasting cap. An example of a blasting agent is the combination of ammonium ...
Blasting caps and detonators play a central role in initiating explosives for mining and quarrying. These small but highly sensitive devices contain primary explosives, such as lead azide or lead styphnate, designed to …
