Spijkenisse First Aid Association

An accident happened in no time. Often cleaning and a plaster is enough, but sometimes it is more serious. And when do you get professional help? In addition, you notice that more and more people are dependent on themselves for a longer period of time before professional help arrives. Knowledge and skills of first aid are very important to provide the best possible help. Knowing what to do and how to do it can make the difference between life and death for a victim.

Energy label

01-10-2021 Energy label

EU Directive 92/75/EC established an energy consumption labelling scheme. The directive was implemented by several other directives thus most white goods, light bulb packaging and cars must have an EU Energy Label clearly displayed when offered for sale or rent. The energy efficiency of the appliance is rated in terms of a set of energy efficiency classes from A to G on the label, A being the most energy efficient, G the least efficient. The labels also give other useful information to the customer as they choose between various models. The information should also be given in catalogues and included by internet retailers on their websites.

In an attempt to keep up with advances in energy efficiency, A+, A++ and A+++ grades were...



01-09-2021 Biodeversity

Biodiversity is the biological variety and variability of life on Earth Biodiversity is a measure of variation at the genetic, species, and ecosystem level Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity Biodiversity is not distributed evenly on Earth, and is richer in the tropics These tropical forest ecosystems cover less than ten percent of earth's surface, and contain about ninety percent of the world's species Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans There are latitudinal gradients in species diversity Biodiversity generally tends...


Co2/Carbon neutral

01-08-2021 Co2/Carbon neutral

Carbon neutrality is a state of net-zero carbon dioxide emissions.
This can be achieved by balancing emissions of carbon dioxide with its removal (often through carbon offsetting) or by eliminating emissions from society (the transition to the 'post-carbon economy').
The term is used in the context of carbon dioxide-releasing processes associated with transportation, energy production, agriculture, and industry.
Although the term 'carbon neutral' is used, a carbon footprint also includes other greenhouse gases, measured in terms of their carbon dioxide equivalence.
The term climate-neutral reflects the broader inclusiveness of other greenhouse gases in climate change, even if CO2 is the most abundant.
The term 'net...

Climate change

Explaining climate change and global warming

The global climate has been changing since time began and will continue to change into the future. The Earth's temperature has fluctuated in the last few hundred years.

Examining the causes of climate change and the greenhouse effect

Past climate change

The Earth's average temperature has changed over the last 500,000 years. There are times when the global climate is warmer (interglacial phases) and times when it has been cooler (glacial phases), when there have been ice ages.

The last major cold period was known as the Pleistocene, started 2.6 million years ago and ended just 10,000 years ago.
Since then, conditions have...


How Dams Are Reshaping the World for the Better and Worse

How Dams Are Reshaping the World for the Better and Worse

You have likely seen a dam before and may even benefit from its energy-producing capacity.
But do you really know what a dam is and how it works?
Do you also know that dams reshape the world around us in incredible ways?

Dams cause earthquakes but they also produce much-needed energy.
Want to hear more about the many current and future dams around the world and their stories both good and bad?

Did you know that China's Three Gorges Dam, for instance, is so massive that it slows the Earth's rotation?
When the dam is at capacity, its reservoir holds 42 billion tons of water which is actually enough to create a shift in mass powerful enough...


The Engineering Behind Cloud Seeding: The Art of Creating Rain

01-05-2021 The Engineering Behind Cloud Seeding: The Art of Creating Rain

The Engineering Behind Cloud Seeding: The Art of Creating Rain
Cloud seeding produces rain by manipulating clouds.

Did you know that countries across the globe are using some sort of weather modification program?
In fact, the technology, although very cutting-edge, has been around for more than 75 years and is only set to grow in popularity as climate change takes its toll on the planet.

One form of weather modification is cloud seeding.
This is a technology that produces rain by manipulating clouds.
The technology can even be used to engineer snow or smaller hail pellets.

How does it work?
Chemicals such as silver iodide, potassium iodide, or solid carbon dioxide (dry ice) are shot into...


Chemtrail conspiracy theory

Chemtrail conspiracy theory

This article is about the conspiracy theory that contrails are deliberate releases of poison.

An Airbus A340's engines leaving a water condensation trail (contrail) - miniature clouds formed by the engine exhaust
The chemtrail conspiracy theory posits the erroneous belief that long-lasting condensation trails are "chemtrails" consisting of chemical or biological agents left in the sky by high-flying aircraft, sprayed for nefarious purposes undisclosed to the general public.
Believers in this conspiracy theory say that while normal contrails dissipate relatively quickly, contrails that linger must contain additional substances.
Those who subscribe to the theory speculate that the...


Earth's Magnetic North Pole Continues Drifting

01-03-2021 Earth's Magnetic North Pole Continues Drifting

Earth's magnetic north pole, which has been wandering faster than expected in recent years, has now crossed the prime meridian.
The team of researchers that maintain the World Magnetic Model (WMM) has updated it and released it a year ahead of schedule due to the speed with which the pole is moving.
The newly updated model shows the magnetic north pole moving away from Canada and toward Siberia.

The magnetic north pole is the point on the Earth that compasses designate as true north.
It is the result of geological processes deep within the planet-molten iron flow creates a magnetic field with poles near the geographic North and South Poles.
But unlike the geographic poles, the magnetic poles can move-and the magnetic...


Planned Obsolescence: How the Products You Buy are Designed to Break

01-02-2021 Planned Obsolescence: How the Products You Buy are Designed to Break

How many times have you bought an electronic device, only to find out that it has stopped functioning properly just a short time after your purchase?

You spent so much money on it, and suddenly you're sad to know that it's not working properly anymore. The result? Wasted expenses, labor, energy and resources, not to mention the toxic waste that ends up in landfills, poisoning our planet.

But why is that so? Why is most product's lifespan so short, considering the advanced, modern technological means of production?

Enter planned obsolescence.

Cyclical Consumption & Planned Obsolescence
Our economic system is based on consumption - the more we buy, the more money moves into the economy, and hence the more the...

E numbers are harmfull

01-12-2020 E numbers are harmfull

Most E numbers in food are bad, there is no doubt of that. This article gives a specific list of substances that are banned in certain countries, and others that are known to provoke allergic reactions in sensitive people.

E numbers ("E" stands for "Europe") are codes for substances used as food additives for use within the European Union (EU) and European Free Trade Association (EFTA). Commonly found on food labels, their safety assessment and approval are the responsibility of the European Food Safety Authority (EFSA).

Having a single unified list for food additives was first agreed upon in 1962 with food colouring. In 1964, the directives for preservatives were added, in 1970 antioxidants were added, in 1974 emulsifiers,...


Aluminum in cosmetics / deodorants / dermal products dangerous to health

01-11-2020 Aluminum in cosmetics / deodorants / dermal products dangerous to health

The potential toxicity of aluminum in cosmetics has been a concern for several years. Often accused of promoting breast cancer or Alzheimer's disease, he was the subject of an assessment by the Afssaps regarding his job security. The Agency has just published its conclusions in an expert report published on 17 November 2011. Conclusion: the risk exists and consumer health safety is not ensured.

The issue has been studied by French health authorities since 2000. In 2003, a first report was published highlighting the lack of relevant data on dermal absorption of aluminum from cosmetic products. It was then impossible to conclude on the risks associated with the use of products containing them.

The assessment published today...


Waste sorting

01-10-2020 Waste sorting

Waste sorting is the process by which waste is separated into different elements.
Waste sorting can occur manually at the household and collected through curbside collection schemes, or automatically separated in materials recovery facilities or mechanical biological treatment systems.
Hand sorting was the first method used in the history of waste sorting.

Waste can also be sorted in a civic amenity site.

"Waste segregation" means dividing waste into dry and wet.
Dry waste includes wood and related products, metals and glass.
Wet waste typically refers to organic waste usually generated by eating establishments and are heavy in weight due to dampness.
Waste segregation is different from waste...
