The product consists of glass particles from 0.5 to 17 microns coated with insecticide that are easily lofted into the air by footsteps and light breezes. Glass dust becomes lodged permanently in the lungs and eyes, where it increases risk of developing cancer and autoimmune disease. Glass dust is expelled from the body slowly through the intestines and kidneys. The active ingredient is cyfluthrin, which is a synthetic neurotoxin fortified by cyanide that may contribute to immune disorders. Chronic disease process can be delayed and could take an extended period of time to develop.

Regulation

Tempo 20 WP is considered to be a hazardous substance, and must satisfy regulatory requirements.

Hazard Communication Standard

Most developed countries have laws and that stipulate workplace health and safety requirements for toxic substances, including government agencies that provide information and enforcement.

Canada

Canada uses the Workplace Hazardous Materials Information System to provide worker protection.
  • Workplace Hazardous Materials Information System

Europe

European Agency for Safety and Health at Work provides information about worker health and safety agencies located in the European Union.

United States

A summary of workers rights is available from OSHA: Employee Workplace Rights.

The Hazard Communication Standard first went into effect in 1985 and has since been expanded to cover almost all workplaces under OSHA jurisdiction. The details of the Hazard Communication standard are rather complicated, but the basic idea behind it is straightforward. It requires chemical manufacturers and employers to communicate information to workers about the hazards of workplace chemicals or products, including training.
  • Hazard Communication Standard
    Hazard Communication Standard
    The Hazard Communication Standard requires employers to disclose toxic and hazardous substances in workplaces. This is related to the Worker Protection Standard....



OSHA's Hazard Communication Standard (HCS) was first adopted in 1983 in the United States with limited scope (48 FR 53280; November 25, 1983). In 1987, scope was expanded to cover all industries where employees are potentially exposed to hazardous chemicals (52 FR 31852; August 24, 1987).

This is managed nationally by the Occupational Safety and Health Administration. When a state has an approved plan, this is managed by that state instead.

The standard is identified in 29 C.F.R. 1910.1200.

The summary for 29 C.F.R. 1910.1200 is as follows.

Employers shall maintain copies of any material safety data sheets ...
and shall ensure that the material safety data sheets are readily
accessible during each work shift to employees when they are in
their work area(s); and,
Employers shall ensure that employees are provided with information
and training ... to detect the presence or release of a hazardous
chemical in the work area ... the physical and health
hazards of the chemicals in the work area ...

The United States Department of Defense does not manage hazards in accordance with public law.

Employers must conduct training in a language comprehensible to employees to be in compliance with the standard. Workers must be trained at the time of initial assignment and whenever a new hazard is introduced into their work area. The purpose for this is so that workers can understand the hazards they face and so that they are aware of the protective measures that should be in place.

When OSHA conducts an inspection, the inspector will evaluate the effectiveness of the training by reviewing records of what training was done and by interviewing employees who use chemicals to find out what they understand about the hazards.

 (MSDSs). Employers whose employees may be exposed to hazardous chemicals on the job must provide hazardous chemical information to those employees through the use of MSDSs, properly labeled containers, training, and a written hazard communication program. This standard also requires the employer to maintain a list of all hazardous chemicals used in the workplace. The MSDSs for these chemicals must be kept current and they must be made available and accessible to employees in their work areas.

Chemicals that may pose health risks or those that are physical hazards (such as fire or explosion) are covered. List of chemicals that are considered hazardous are maintained according to the use or purpose. There are several existing sources that manufacturers and employers may consult. These include:
  • Any substance for which OSHA has a standard in force, including any substance listed in the Air Contaminants regulation.
  • Substances listed as carcinogens (causing cancer) by the National Toxicology Program (NTP) or the International Agency for Research on Cancer (IARC).
  • Substances listed in the Threshold Limit Values for Chemical Substances and Physical Agents, published by the American Conference of Governmental Industrial Hygienists (ACGIH).
  • Restricted Use Products (RUP) Report; EPA


There are other sources of information about chemicals used in industry as a result of state and federal laws regarding the Community Right to Know Act.

The Air Resources Board is responsible for public hazard disclosures in California. Pesticide use disclosures are made by each pest control supervisor to the County Agricultural Commission. Epidemiology information is available from the California Pesticide Information Portal, which can be used by health care professionals to identify the cause for environmental illness.

Under the Oregon Community Right to Know Act (ORS 453.307-372) and the federal Superfund Amendments and Reauthorization Act (SARA) Title III, the Office of the State Fire Marshal collects information on hazardous substances and makes it available to emergency responders and to the general public. Among the information which companies must report are:
  • Inventories of amounts and types of hazardous substances stored in their facilities.
  • Annual inventories of toxic chemicals released during normal operations.
  • Emergency notification of accidental releases of certain chemicals listed by the Environmental Protection Agency.

The information can be obtained in the form of an annual report of releases for the state or for specific companies. It is available on request from the Fire Marshal’s Office and is normally free of charge unless unusually large quantities of data are involved.

 and state regulatory agencies.

Two items are requited by law for all registered pesticides and insecticides.
  • Product Label
  • Material Safety Data Sheet


The product label describes how to use the product.

The Material Safety Data Sheet provides specific safety and hazard information, and this must be provided to physicians in the event that the product has been miss-used so that appropriate diagnostic testing and treatment can be obtained in a timely manner.

RUP requires license for purchase. The process required to obtain a pest control licenses is regulated by a combination of state laws, federal laws, common law, and private company policies.

All RUP applications must be recorded to identify the date, location, and type of pesticide applied. Federal law requires a minimum record retention period, which may be 3 years or longer depending upon state laws.

There are two categories of license: supervisor and applicator. A pest control supervisor license is required to purchase RUP and keep records. The pest control supervisor must ensure pest control applicators are competent to use any restricted use products.

 when Restricted use pesticide is applied.

The list of restricted use pesticides is maintained by the US EPA.

Additionally, specific environmental pollutants are identified in public law, which extends to all hazardous substances even if the item is not identified as a restricted use pesticide by the EPA. As an example, cyfluthrin, cypermethrin, and cynoff contain cyanide, which is one of the most toxic substances known to man, but some of the products that contain these chemicals may not be identified as restricted use pesticide.

Some specific chemicals, such as cyaniate, cyanide, cyano, and nitrile compounds, satisfy the specific hazard definition that is identified in public law regardless of whether or not the item is identified on the list of restricted use pesticides maintained by the United States Environmental Protection Agency.

Risks

There are multiple chemical risks associated with Tempo WP products, which contain the following.

Cyfluthrin

Cyfluthrin
Cyfluthrin

" laws governing public health.

Pyrethroids are detoxified to some extent by the liver when ingested. Human skin tends to block pyrethroids, which are not absorbed rapidly. Cyfluthrin can cause numbness, itching, burning, stinging, and tingling following skin and mucous membrane contact. Lips, tung, sinus, throat, lungs, and eye tissue may swell. The onset of symptoms can take 1 or 2 days to appear after initial exposure but symptoms may also occur during exposure or within a few hours. Sweating or exposure to sun or heat may make skin irritation worse. Repeated exposure can make symptoms worse.

Cyfluthin is absorbed readily during inhalation exposure where it is not detoxified by the liver. Aerosol and particle exposure can be fatal. Inhalation toxicity tests with rats shows "Median lethal dose" is greater than 1,089 ug/l in 1 hour tests, and ranged from 469 - 592 ug/l in 4 hour tests for the chemical cyfluthrin.

Cyfluthrin is the root cause of a number of industrial injuries that occur every year due to inadequate worker protection and improper public safety.

Glycol

The type of glycol used in Tempo 20 WP is considered to be a trade secret. The amount of glycol used in Tempo 20 WP is not hazardous by itself.

Glycol is hygroscopic and absorbs water vapor from the atmosphere. This activates the acidic properties of lignosulfonic acid, sodium salt.

Lignosulfonic acid, sodium salt

Lignosulfonic acid, sodium salt has the following properties:
  • CAS# 8061-51-6
  • Flammable.
  • Explosive when disbursed as a dust in air.
  • Strong oxidizing acid.
  • Violent exothermic reaction when mixed with water (becomes extremely hot).
  • Reacts with cyanide salts and cyanide related compounds to release gaseous hydrogen cyanide.
  • Flammable and/or toxic gases are also often generated by reaction with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and weak or strong reducing agents.

 is a dry powder acid that magnifies the lethality of Tempo 20 wp by creating cyanide gas.

Cyanide

Hydrogen cyanide is released from cyfluthrin due to the action of lignosulfonic acid, sodium salt when damp, such as with fog, with morning dew, with the moisture provided by the hygroscopic action of glycol in humid air, when inhaled, and when in contact with the surface of the eye. Half the cyanide gas in cyflutrhin is released within 3 days of exposure to air and ultraviolet light, and acid accelerates this process.

Cyanide exposure plays a role in immune system injury. Exposure limits listed here and in product safety literature are "one time limits" that do not provide protection for repeated exposure that is associated with the development of the following health issues:
  • Hypersensitivity
    Hypersensitivity
    Hypersensitivity refers to undesirable reactions produced by the normal immune system, including allergies and autoimmunity. These reactions may be damaging, uncomfortable, or occasionally fatal. Hypersensitivity reactions require a pre-sensitized state of the host. The four-group classification...

  • Asthma
  • Chronic bronchitis


Cyanide is one of the fastest acting and most lethal toxins known to man. According to the Agency for Toxic Substances and Disease Registry, inhalation exposure of over 546 ppm of hydrogen cyanide is fatal within 10-minutes, and 110 ppm is considered life-threatening within one hour. Cyanide inhalation can mimic heart attack and stroke because the most sensitive tissue for cyanide asphyxiation are cardiac muscle and brain tissue.

The liver processes cyanide and reduces toxicity to some extent when ingested.

Inhaled cyanide products are not detoxified by the liver. The 8 hour workplace exposure limit is no more than 10 ppm (11 mg/m3) of air.

Toxicity and lethality depends upon the route of entry into the body.

OSHA recommends 15 CFM fresh air circulation in buildings. Cyanide accumulate inside closed structures that lack proper ventilation as cyfluthrin degrades.

The cyanide content of cyfluthin can contribute to the development of hypersensitivity disease, autoimmune disease, Alzheimer's disease, and other serious illnesses following repetitive sub-lethal exposure.

Cyanide exposure plays a role in neurological diseases, such as multiple sclerosis, Alzheimer's, and dystonia.

Glass Dust

Glass dust may also be known as rock dust, quartz dust, and silicon dioxide. The CAS# is 14808-60-7

Respirators are required to prevent inhalation of powdered silica dust. The treatment after inhalation is to keep airways open and provide oxygen.

This is considered to be a hazardous substance by US Department of Transportation and US Environmental Protection Agency, and it is carcinogenic under California Proposition 65.

Inhaling finely divided crystalline silica dust in very small quantities (OSHA allows 0.1 mg/m3) over time causes silicosis, bronchitis, and cancer. The dust is lodged in the lungs and continuously irritates them causing cellular tissue damage reducing air capacity. Silica particles do not dissolve over clinically relevant periods of time. This creates a hazard for people exposed to products that contain powdered crystalline silica. Children, asthmatics of any age, allergy sufferers, and the elderly (all of whom have reduced lung capacity) can be affected in much less time. Amorphous silica, such as fumed silica is not associated with development of silicosis, but may cause irreversible lung damage in some cases. Laws restricting silica exposure with respect to the silicosis hazard specify that they are concerned only with silica that is both crystalline and dust-forming, which is the type used with Tempo 20 WP.

Inhalation risks

  • Silicosis: Respirable crystalline silica (quartz) can cause silicosis, a fibrosis (scarring) of the lungs. Silicosis may be progressive; it may lead to disability and death.
  • Lung Cancer: Crystalline silica (quartz) inhaled from occupational sources is classified as carcinogenic to humans.
  • Tuberculosis: Silicosis increases the risk of tuberculosis.
  • Autoimmune Diseases: Some studies show excess numbers of cases of scleroderma, connective tissue disorders, lupus, rheumatoid arthritis, chronic kidney diseases and end-stage kidney disease in workers exposed to respirable crystalline silica.
  • Chronic Kidney Diseases. Several studies report excess cases of kidney diseases, including end stage renal disease, among silica-exposed workers.
  • Non-Malignant Respiratory Diseases (other than silicosis): Some studies show an increased incidence in chronic bronchitis and emphysema in workers exposed to respirable crystalline silica.

Eye contact

Crystalline silica (quartz) causes corneal abrasion and can become permanently lodged in the eye.

Magnesium aluminum silicate

Magnesium aluminum silicate is not considered to be a hazardous substance by US Department of Transportation and US Environmental Protection Agency, and it is not considered to be carcinogenic under California Proposition 65.

Aluminum is one of the non-protein components of amyloid plaque associated with Alzheimer's disease. Silicon is associated with increase risk of cancer and osteoporosis. Magnesium aluminum silicate contains both.

Do not breathe. The treatment after inhalation is to keep airways open and provide oxygen. A self contained breathing apparatus should be used to avoid inhalation.

Inhaling fine dust particles in very small quantities over time can lead to bronchitis

, or other diseases. In the body, magnesium aluminum silicate particles dissolve slowly and may form mud, which may be expectorated from the lungs and ingested. This exposes the body to silicon and aluminum that can pose health risks. Children, asthmatics of any age, allergy sufferers, and the elderly (all of whom have reduced lung capacity) can be affected in much less time.

Inhalation risks

  • Alzheimer's: Respirable and ingested magnesium aluminum silicate may contribute to Alzheimer's disease.
  • Osteoporosis: Respirable and ingested magnesium aluminum silicate may contribute to osteoporosis.
  • Non-Malignant Respiratory Diseases (other than silicosis): Some studies show an increased incidence of chronic bronchitis and emphysema associated with magnesium aluminum silicate
