Cypher Environmental has completed the creation of a technical specification (TS) that offers standardization (simplification, unification, specification) of airstrip dust control and soil maintenance processes as well as their correct application and ethical development.
Supported and guided by the Standards Council of Canada (SCC), we have followed standardized processes through the creation of a DUST/BLOKR® Airstrip Maintenance Technical Specification.
DUST/BLOKR® is a non-corrosive and environmentally friendly alternative to road salts such as magnesium chloride and calcium chloride. DUST/BLOKR® offers superior road dust control results for a number of applications from airstrip and aviation to agriculture and mining.
This document was developed and endorsed by members of our working group including end users, implementors and vendors, and technical solution experts.

What is DUST/BLOKR®?
DUST/BLOKR® is specifically designed as a non-corrosive and environmentally friendly alternative to road salts such as magnesium chloride and calcium chloride, oil-based or cement/lime-based dust suppressants. DUST/BLOKR® is able to provide superior road dust control results without damaging the environment. DUST/BLOK is relatively cost-competitive when compared to traditional dust suppressants that are used to control airstrip or runway dust. DUST/BLOKR can eliminate up to 90% of unwanted fugitive dust from unpaved roads or airstrips composed of almost any soil type.

Stabilization Performance
Criteria: CBR Gain
The product must provide increased bearing strength (CBR) and light surface stabilization.
Petroleum Distillates
Criteria: 0% Petroleum distillates
The product must not contain any petroleum distillates. The ingestion or inhalation of, or skin contact with, petroleum, petroleum condensate, gasoline, diesel fuel, kerosene, crude oil, or other hydrocarbon mixtures may cause illness and occasionally death in domestic and wild animals.

Post Application Surface Watering
Surface water treatment must not be required post application.
Aquatic Toxicology
Criteria: 96-hour LC50 v/v(%) Non lethal
The following testing standards shall be used to determine the aquatic toxicity of the product.
- EPS 1/RM/13, 2nd Ed. Dec. 2000, with 2007 and 2016 amendments, Environment Canada
- EPS1/RM/9, May 1996 with May 2007 amendments, Environment Canada
The test uses certified, disease-free rainbow trout (Oncorhynchus mykiss) that are exposed to several concentration of a sample, including full strength, under static conditions in order to estimate the median lethal concentration (LC50) – the concentration of the sample in water that is estimated to be lethal to 50% of the test organism within a 96-hour exposure period. The product shall demonstrate a non-lethal impact after 96 hours.
