Water Purification

For small quantities of water, preparing a master solution is an easy and effective approach. Here’s how you can do it:

Example: To purify 1 quart (32 ounces / 1 liter) of water, you will need two containers of the same size (1 quart / 32 ounces / 1 liter) each.

⁃ Prepare a Master Solution: Dissolve 1 tablet in 1 quart (32 ounces / 1 liter) of water to create a solution with a concentration of 100 PPM.
⁃ Treat the Water: Add approximately 1.7 ounces (50 ml), which is about 1/10th of the recipient, to the second container with 1 quart (32 ounces / 1 liter) of water. You obtain a 5 PPM concentration.

To confirm the success of the treatment, make sure the treated water has a faint chlorine smell, as this indicates proper disinfection. If no odor is detected, add a small additional amount of the master solution and recheck.

A dosage of 5 PPM is recommended for storing water in emergency situations. This concentration is effective for keeping the water clean and safe for extended periods.

For containers not exposed to sunlight:
Add tablets every 15 days. If the water is stored in a cool, dark place like a basement, it can remain clean for several weeks. While adding tablets every 2 weeks is recommended for safety, the water may actually stay drinkable for longer periods. If you plan to be away for an extended time, consider doubling the dosage before you leave to ensure the water remains safe.
For containers exposed to sunlight:
Add tablets every 7 days to maintain the water’s quality.

Additionally, UPS does not deliver to PO boxes in Canada. To avoid any delays, please provide a street address for delivery.

SHELF LIFE

Once opened, Safrax tablets typically have a shelf life of about 30 days due to their high sensitivity to humidity. In some cases, they may last 60-90 days, but we recommend planning for 30 days to be safe. When exposed to moisture, the tablets can absorb humidity, swell, become powdery, and lose effectiveness.
The POOL and DISIN packages now come with five 100-tablet packs inside the outer bag, making them ideal for extending shelf life if you use the tablets more slowly. 
Additionally, the new “SURVIVAL BAG” which contains 120 individually wrapped tablets, is a great option for slow consumption.
 
To maximize shelf life, transfer the opened bag (still inside its original Safrax outer wrapping) into an airtight container. 
For the best results, store the tablets in a glass or plastic jar with a screw-type plastic lid that has an inner seal, such as a canning jar. We’ve found that old peanut butter jars work well for this purpose. Keep the container in a closed cabinet, away from children. 
Adding one or two humidity-absorbing packets can further extend shelf life. 
 
Note: Storage methods like vacuum sealing have not been shown to significantly extend the shelf life of opened bags. Some users have reported getting an extra month with these methods, but we cannot guarantee the results.

Unopened bags of Safrax tablets have a shelf life of over 5 years.

SEPTIC TANK

Yes, Safrax Chlorine Dioxide can help eliminate bad odors from a septic tank, which are usually caused by an imbalance in the tank’s bacterial population. To address the issue, you can pour small amounts of a chlorine dioxide solution down the drain as follows:
 
1. Start with 1 liter of water mixed with 10 tablets of Safrax Chlorine Dioxide.
 
2. Pour the solution gradually into the septic system and wait to see if the odor dissipates.
 
3. If the odor persists, you can add more of the solution in small increments until the smell stops.
 
Once the odor is resolved, stop using the solution to avoid over-treating the tank.
Safrax Chlorine Dioxide is safe for septic systems as long as you’re not consistently pouring high concentrations (PPM) into the tank on a daily basis. Standard household use of ClO2, in concentrations ranging from 100 PPM to 500 PPM, will not harm the beneficial bacteria in your septic system.

GAS TREATMENT

Safrax Chlorine Dioxide gas is not corrosive, but certain precautions are necessary to avoid potential damage:

• Keep the container used for mix the solution at least 5 feet away from stainless steel surfaces, such as a stainless steel refrigerator. 

• Ensure all metal and stainless steel surfaces are completely dry before starting the gas treatment.

• Gardening tools and other metal objects can be affected by the gas and may develop rust. If this occurs, simply clean the items after the treatment.

• Electronic equipment, such as in server rooms, is not typically affected by the gas, as these environments are kept very dry.

CORROSION

Chlorine dioxide does not corrode most plastic containers. Materials like high-density polyethylene (HDPE) and polypropylene (PP) are suitable for storing chlorine dioxide solutions, as they are resistant to chemical reactions with ClO2 and are commonly used for this purpose. However, prolonged exposure to high concentrations of chlorine dioxide can cause plastic containers to develop a yellowish discoloration.

Yes, Safrax Chlorine Dioxide can be corrosive to plumbing pipes made of copper, galvanized iron, or cast iron, particularly at high concentrations or with prolonged exposure.
However, at low concentrations (such as 20 PPM or lower), it is not corrosive.
If you need to use a higher concentration, such as 500 PPM, it is recommended to limit the exposure time to just a few hours. Afterward, thoroughly flush the pipes for a few minutes with water to minimize the risk of corrosion.

 Yes, chlorine dioxide can corrode thin layers of most metals, including stainless steel.
Stainless Steel 316 is more resistant to corrosion and can withstand exposure to chlorine dioxide better than other grades.
Stainless Steel 304, is more susceptible to corrosion. If chlorine dioxide tablets are placed directly into water inside a 304 stainless steel tank, the area where the tablets settle may become stained and could corrode over time, leading to pitting or even small holes. Corrosion occurs primarily when the tablets come into direct contact with the stainless steel as they dissolve.


To prevent corrosion, avoid placing the tablets directly in the tank. Instead, dissolve the chlorine dioxide tablets in water first, then add the prepared solution to the 304 stainless steel tank.

 Yes, Safrax Chlorine Dioxide can degrade certain lower-quality or delicate metals, such as thin screws, and may potentially damage sensitive components when used on machines, motors, or electronics. When disinfecting with high concentrations (e.g., 100 PPM or higher), it is important to thoroughly wipe down or rinse the surfaces afterward to minimize the risk of corrosion or damage.

Safrax Chlorine Dioxide gas is not corrosive, but certain precautions are necessary to avoid potential damage:

• Keep the container used for mix the solution at least 5 feet away from stainless steel surfaces, such as a stainless steel refrigerator. 

• Ensure all metal and stainless steel surfaces are completely dry before starting the gas treatment.

• Gardening tools and other metal objects can be affected by the gas and may develop rust. If this occurs, simply clean the items after the treatment.

• Electronic equipment, such as in server rooms, is not typically affected by the gas, as these environments are kept very dry.

CARPET CLEANING

Safrax® Chlorine Dioxide is an effective solution for removing odors from carpets and upholstery in rental units, lobbies, and other common areas. It is especially useful for eliminating stubborn odors like smoke, pet odors, or musty smells.
Safrax® Chlorine Dioxide can be applied directly to carpet fibers through various methods, including spraying or injection, to target specific problem areas. 
It can also be used in a carpet cleaning machine to clean and disinfect carpets quickly and efficiently. Here are the general steps for using chlorine dioxide in a carpet cleaning machine:
 
1. Dilute the Chlorine Dioxide Solution:
Prepare the solution according to the required concentration (PPM). Always test the solution on a small, inconspicuous area of the carpet before treating the entire surface, as chlorine dioxide can sometimes cause discoloration (similar to bleach) on certain types of carpets: 
    – General Treatment: 500 to 1,000 PPM  (To achieve a concentration of 500 PPM, add 5 tablets to 32 ounces of water. For a concentration of 1,000 PPM, add 10 tablets to 32 ounces of water).
    – Pet Urine Treatment: 2,000 to 3,000 PPM  (To achieve a concentration of 2000 PPM, add 20 tablets to 32 ounces of water. For a concentration of 3,000 PPM, add 30 tablets to 32 ounces of water, be cautious of ClO2 gas fumes when adding 20 to 30 tablets to 32 ounces of water. Avoid inhaling the fumes. As a precaution, wear a mask or respirator while mixing the solution.).
 
2. Fill the Carpet Cleaning Machine:
    Pour the diluted chlorine dioxide solution into the machine’s solution tank.
 
3. Clean the Carpet:
Clean the carpet as usual, focusing on heavily soiled or stained areas. Ensure that the solution is applied evenly across the entire carpet. Allow the solution to sit for a few minutes to penetrate the carpet fibers, while using the machine’s brushes to help distribute the solution and loosen dirt or debris.
 
4. Extract the Solution:
    Use the machine’s suction system to thoroughly extract the solution from the carpet.
 
Important:  Safrax® Chlorine Dioxide may discolor organic fabrics, so be sure to perform a spot test first.
