Dust You Cannot See, Fire You Cannot Afford: Combustible Dust Control in Blast Rooms

The fine fraction produced inside a blast room is rarely inert, and in a confined enclosure it behaves very differently from the same dust outdoors. This article examines how spent media and coating debris accumulate, what DSEAR expects of a blast room operator, and which housekeeping, ignition-control and fire-watch arrangements hold up under scrutiny.

Second-Hand Blast Pots: Twelve Checks That Separate a Bargain From a Liability

A used blast pot can be the best value purchase a small blasting firm makes, or the most expensive one. This guide sets out the paperwork, shell measurements, control-system tests and valve inspections that should happen before money changes hands — and explains why the ticket price is only the beginning of the arithmetic.

The Perimeter Is Part of the Job: Containment, Noise and Access on Urban Blast Sites

On city-centre and occupied-building projects, the blast enclosure is only one part of the boundary that needs managing. This field guide sets out a practical approach to containment screens, dust and noise control, neighbour liaison and emergency access, with a one-page checklist for the site boundary.

Air Behind the Abrasive: Sizing Compressors, Hoses and Nozzles for Stable Blast Pressure

An undersized air system rarely fails outright; it simply delivers less pressure, slower work and a less consistent finish. This explainer sets out how to calculate nozzle demand, account for hose losses and choose a compressor, hose and nozzle combination that holds pressure through the shift.

Grain, Grit and Caution: Low-Pressure Blasting on Listed Stone, Brick and Render

Cleaning historic fabric is a conservation decision before it is a blasting decision. This guide covers trial panels, media and pressure selection, containment in sensitive locations, and the documentation that convinces a conservation officer and a client at the same time.

Priced on Proof, Not on the Clock: Why Surface Preparation Should Be Sold as an Outcome

Hourly rig rates remain the default in UK surface preparation, yet they reward attendance rather than achievement and leave both parties exposed when a job runs long. This piece sets out the commercial case for quoting against measurable outcomes and explains how to build a contract that holds up under scrutiny.

From Hopper to Handover: Building a Defensible Waste Trail for Spent Abrasive and Coating Debris

Classification problems on blasting projects rarely begin at the skip; they begin at the survey. This operational guide sets out how to assess, segregate, label and record spent abrasive so that the waste leaving site is described accurately the first time and the paperwork holds together at audit.

Between Nozzle and Primer: Controlling the Corrosion Window on Blasted Steel in British Weather

A blast-clean surface is chemically eager to oxidise, and a British autumn will happily oblige. This guide sets out how contractors can measure, control and document the interval between blasting and priming so that a substrate never leaves the yard in a condition the client did not pay for.
