In the wake of emergencies, a gas mask can be your lifeline, filtering out harmful substances from the air. Crafting your own gas mask might seem daunting, but with simple materials and clear instructions, anyone can create a rudimentary one. Let's delve into the process of drawing and crafting a basic gas mask.
Before we dive into the details, let's understand what makes a gas mask effective. Primarily, it consists of a facepiece sealed against the skin, a filter canister to remove toxins, and a means to secure it to the user's head. Now that we have the basics let's explore how to draw and create a simple gas mask.
Drawing the Gas Mask
The first step in creating a gas mask is visualizing its design. Grab a pencil and some paper, and let's start drawing a basic gas mask.
Gas masks usually come in two types - full-face and half-face. For simplicity, we'll draw a half-face mask, covering the nose and mouth.
Sketching the Facepiece
Begin by drawing an oval to represent the face. From the center of this oval, draw a horizontal line to represent the mouth. Just above this line, draw two small ovular shapes to represent the eyes. Next, sketch two curved lines from the top of the first oval downwards to create a-second, smaller oval, representing the chin.
From the bottom of the smaller oval, draw two lines going straight down, then curve them inward to meet the bottom of the first oval. This will create the neck. Finally, add details like the shape of the mask that fits over the mouth and nose.
Incorporating the Filter Canister
Add a rectangle behind the sketched face, measurements should be adjustable as per the actual filter canister size. This will be the space where the filter canister attaches.
Draw a cylinder at the end of the rectangle, larger in diameter to accommodate the gas mask filter. In the final crafting stage, this is where you will insert the filter canister.
Creating the Gas Mask
Now that we have a drawn reference, let's explore how to craft a basic gas mask using easily accessible materials.
The primary components needed are a filter canister, facepiece, and straps. For a DIY mask, using a 3D printer, an air filter, and elastic bands can do the trick initially, but remember, this will not replace a certified medical gas mask.
Fabricating the Facepiece
The facepiece can be made of various materials like plastic, rubber, or at the most basic level, a plastic bottle. Using a 3D printer to craft the facepiece would be ideal, as it allows precise shaping to fit the face. Draw your design on a 3D modeling software, and use the 3D printer to create a real model.
In absence of a 3D printer, you can carve the shape from a plastic bottle. The bottle's wide end will cover the mouth and nose, with the narrow end working as the framework for mounting the filter canister.
Preparing the Filter Canister and Straps
Use a plastic container or a Migration Health Kit (MHK) filter, if available, as the filter canister. If you're not using an MHK filter, you can pack activated carbon, which is good at absorbing many gases, into the canister.
Use elastic bands or Velcro straps to secure the mask to the wearer's face. Ensure the fit is secure yet comfortable. Fit the canister to the mask using a simple screw thread produced by your 3D printer or by glue-gunning a rubber hose in between.
Remember, this is a basic gas mask, not a substitute for certified medical equipment. Always use certified gas masks in real-life situations. Now that you've crafted your DIY gas mask, keep it in a safe, accessible place, and hold regular drills to check its functionality and your comfort level with it. Stay safe and prepared.
