Ask before you guess.

You do not need to be an expert. Introduce yourself, find out what is happening, ask questions and learn from the people already using the space.

First visit checklist

  • Introduce yourself to someone in the space.
  • Ask what activities, workshops or projects are happening.
  • Find out which areas and tools you are allowed to use.
  • Ask another member if you are unfamiliar with a tool or process.
  • Keep your work area organised and leave it ready for the next person.
BE CURIOUSQuestions are welcome.
BE CAREFULUnderstand a tool before using it.
BE CONSIDERATEShared resources belong to the community.
BE A BUILDERHelp improve the space.
02 / SHARED SPACE

Using the Space

OBS is shared by many people. Your work should make it easier—not harder—for the next person to use the space.

01

Find your area

Use the appropriate bench, workshop, meeting area or storage location for your activity.

02

Protect shared resources

Do not move equipment, tools or community supplies without knowing where they belong.

03

Clean as you work

Remove scraps, wipe benches and return tools instead of leaving a cleanup job for someone else.

04

Report problems

Tell another member when equipment is damaged, unsafe, missing or behaving unexpectedly.

SHARED SPACE RULE

If your project takes up space for more than one session, label it clearly and store it in an agreed location. Do not assume an unattended project is available for others to use.

03 / WORKSHOP

Tools & Equipment

OBS can contain ordinary hand tools, tool kits, workshop equipment and specialised machines. Safe use starts with orientation.

Before using a tool

  1. Know what it does. Read the label or guide and understand the intended use.
  2. Ask if you are new to it. Another member can show you the safe operating procedure.
  3. Inspect it. Look for damaged cables, loose parts, broken guards or other hazards.
  4. Use the right protection. Wear appropriate eye, hearing, hand or respiratory protection where required.
  5. Power down after use. Switch off, unplug or isolate equipment when the activity is complete, as appropriate.

The same rule applies to borrowing: know where the item belongs, return it clean and complete, and report anything that needs repair or replacement.

04 / NETWORKING LAB

  • Ask for an orientation if you have never operated the printer.
  • Keep hands away from moving and hot parts.
  • Do not leave a failed or dangerous print running unattended.
  • Remove your print and clean the build area when finished.
  • Power down only according to the printer's normal shutdown procedure.

CNC, machine tools & digital fabrication

SPECIALISED EQUIPMENT

Never learn a powered machine by trial and error. Ask an experienced member for an orientation before operating it.

  • Use guards and emergency-stop controls as instructed.
  • Wear required PPE and secure loose clothing, hair and jewellery.
  • Keep hands clear of cutting, drilling and moving mechanisms.
  • Check the material is suitable for the machine and securely fixed.
  • Keep the work area clear of unnecessary people and objects.
  • Switch off or isolate equipment before cleaning, changing tooling or clearing a jam.
  • Clean the machine and surrounding area after use.

Crafts, art & textiles

  • Choose a workspace suitable for cutting, gluing, painting, sanding or other processes.
  • Ask before using unfamiliar powered tools or chemicals.
  • Provide ventilation when a process creates fumes, dust or strong odours.
  • Ask for an orientation before using an unfamiliar sewing machine.
  • Keep fingers away from needles and moving mechanisms.
  • Switch off sewing equipment before threading, changing a needle or clearing a jam.
  • Store fabric, offcuts and sharp tools safely.
  • Clean lint, scraps and other waste from the work area after use.

Materials & digital fabrication practice

  • Confirm that the material is compatible with the machine and process.
  • Use the correct settings for the material and process.
  • Ask for machine-specific training before using unfamiliar equipment.
  • Do not bypass interlocks, guards or ventilation systems.

Food storage

Personal non-perishable storage

Members may keep personal non-perishable food in designated personal containers. Label your container clearly with your name and keep it in the agreed storage area.

Community food storage

OBS may maintain a shared container of community food items that members can freely take from. If you use something, consider replacing or contributing to the shared supply when you can.

The fridge is shared

Any food placed in the community refrigerator should be treated as available for use by other members. Do not put food in the shared fridge if you expect it to remain exclusively yours.

Fresh food

Fresh items kept in the shared kitchen may be used by members. Label or separate items only where OBS has an agreed system for personal storage.

COOKING SAFETY

New to a kitchen tool? Ask another member to show you how to use it. This helps prevent injury, damage to the equipment, fire or damage to the space.

Before, during and after preparing food

  • Wash hands and keep preparation surfaces clean.
  • Use appropriate utensils and handle knives, heat and appliances carefully.
  • Ask for help if you are unfamiliar with a cooker, oven, microwave, blender or other kitchen equipment.
  • Do not leave cooking equipment operating unattended when doing so creates a safety risk.
  • After preparing a meal, switch off appliances and equipment that should be turned off.
  • Clean utensils, surfaces and equipment after use and return them to their proper locations.
  • Dispose of food waste appropriately and do not leave spoiled food in shared storage.
  • Respect allergies, dietary restrictions and other members' food.
COMMUNITY FOOD PRINCIPLE

If you want a food item to remain exclusively yours, keep it in your labelled personal non-perishable container or another clearly agreed personal storage arrangement. Food placed in the shared fridge should be understood as potentially available to other members.

09 / RESPONSIBLE SECURITY

Security Lab

Cybersecurity at OBS is for learning, defensive experimentation and responsible research in systems where you have permission.

AUTHORISED TESTING ONLY

Do not attack, scan, intercept, disrupt or attempt to access systems, accounts, networks or devices without permission.

  • Use intentionally vulnerable or isolated systems for practice.
  • Do not collect or expose another person's credentials or private data.
  • Keep experiments separated from shared production infrastructure.
  • Document what you changed so systems can be restored.
  • Report vulnerabilities responsibly rather than exploiting them.
  • Ask another member if you are unsure whether an activity is authorised.
10 / COMMUNITY EVENTS

Event Hosting

OBS events can be workshops, talks, build sessions, screenings, repair days, game nights or community meetups.

11 / KNOWLEDGE SHARING

Project Documentation

Good documentation lets another member understand what you built, reproduce it, repair it or continue it after you leave.

DOCUMENT / SHARE / IMPROVE

Leave a useful trail.

Document enough for another person to pick up the project without having to start from zero.

What to record

  • Project goal
  • Materials and components
  • Tools and equipment
  • Design files and code
  • Steps and configurations
  • Problems and solutions
  • What you would change next time

Where to put it

  • Use the agreed OBS documentation space.
  • Use clear file names and dates.
  • Include diagrams or photos where they explain something better than text.
  • Credit contributors and respect licences.
12 / END OF SESSION
