Some of you may be familiar with OSHA - the Occupational Safety & Health Administration. The sole purpose of this agency is to keep American workers safe. Complying with OSHA regulations isn't always easy, but if we work together, we can do it. Yet, complying with regulations is not the real reason for working safely. Our real motive is simple. We care about each and every one of you and will do what is necessary to prevent you from being injured.
However, keeping our workplace safe takes input from everyone. Management, supervisor, and all of you have to come together on this issue, or we're in trouble. For example, upper management has to approve the purchase of safe equipment. Supervisors, including myself, have to ensure that each of you knows how to use that equipment safely. Then it's up to you to follow through the task and use the equipment as you were trained. If any one part of this chain fails, accidents are going to happen and people are going to get hurt.
Responsibility Number One - Recognize Hazards
At the core of your safety responsibilities lies the task of recognizing safety and health hazards. In order to do that, you must first understand what constitutes a hazard. Extreme hazards are often obvious. Our hopes are that you won't find too many of those around here.
There are, however, more subtle hazards that won't jump up and bite you. As a result of your safety training and meetings like these, some things may come to mind. For example, a machine may not be easy to lock out. Common practice may be to use a tag. This is a potential hazard and should be discussed. Maybe something can be changed to make it easier to use a lock. Other subtle hazards include such things as frayed electrical cords, a loose machine guard, a cluttered aisle, or maybe something that just doesn't look right.
Responsibility Number Two - Report Hazards
A big part of recognizing hazards is using your instincts. Nobody knows your job as well as you do, so we're counting on you to let us know about possible problems. Beyond recognizing hazards, you have to correct them or report them to someone who can. This too, is a judgement call. For example, if something spills in your work area you can probably clean it up yourself. However, if there is an unlabeled chemical container and you have no idea what it is, you should report it to your supervisor.
Additional Employee Responsibilities
Good housekeeping is a major part of keeping your work area safe. For example, you should take a few minutes each day to ensure that aisles, hallways, and stairways in your work area are not obstructed. If boxes, equipment, or anything else is left to pile up, you have a tripping hazard on your hands. Those obstructions could keep you from exiting the building quickly and safely should you face an emergency situation.
Also watch out for spills. These can lead to slips and falls. Flammable materials are another thing to be aware of. Make sure they are disposed of properly.
Keep Thinking. Even if you're doing your job safely and you are avoiding hazards, there are often even better ways to work safely. If you have ideas for improving the safety of your job or that of co-workers, share them.
Concluding Remarks
While nothing we do can completely eliminate the threat of an incident, we can work together to improve our odds. As I said, this must be a real team effort and I'm counting on input from all of you. Let's keep communicating and continue to improve safety.

WASHINGTON — Getting blood or other perishable supplies to an area that’s been struck by an earthquake or hurricane isn’t as simple as asking what brown can do for you. But a new model quickly determines the best routes and means for delivering humanitarian aid, even in situations where bridges are out or airport tarmacs are clogged with planes.
The research, presented February 18 at the annual meeting of the American Association for the Advancement of Science, could help get supplies to areas which have experienced natural disasters or help prepare for efficient distribution of vaccines when the flu hits.
Efficient supply chains have long been a goal of manufacturers, but transport in fragile networks — where supply, demand and delivery routes may be in extremely rapid flux — requires a different approach, said Anna Nagurney of the University of Massachusetts Amherst, who presented the new work. Rather than considering the shortest path from one place to another to maximize profit, her system aims for the cleanest path at minimum cost, while capturing factors such as the perishability of the product and the uncertainty of supply routes. ‘You don’t know where demand is, so it’s tricky,’ said Nagurney. ‘It’s a multicriteria decision-making problem.’
By calculating the total cost associated with each link in a network, accounting for congestion and incorporating penalties for time and products that are lost, the computer model calculates the best supply chain in situations where standard routes may be disrupted.
‘Mathematical tools are essential to develop formal means to predict, and to respond to, such critical perturbations,’ said Iain Couzin of Princeton University, who uses similar computational tools to study collective animal behavior. ‘This is particularly important where response must be rapid and effective, such as during disaster scenarios … or during epidemics or breaches of national security.
’ The work can be applied to immediate, pressing situations, such as getting blood, food or medication to a disaster site, or to longer-term problems such as determining the best locations for manufacturing flu vaccines. . Retrieved April 7th, 2011.

TEXT 1
At least 200 people have died in the Brazilian state of Rio de Janeiro after another storm. This is arguably the worst torrential rain for decades, causing flooding and landslides. Our website readers in Rio de Janeiro have been sharing their experiences.
Comment 1 - I’ve never seen such chaos. We weren’t prepared for this, even though we were warned that a big storm was about to come. Newspapers are saying that the reason for the catastrophe is the garbage. Well it may have been. We need to teach recycling at schools and community groups, otherwise we will have more disasters like this. (Lia, Niterói)
Comment 2 - Today I witnessed Rio de Janeiro on the brink of collapse. I ventured out around midday, just as the electric power blacked out in my neighbourhood. Three hours later, looking out of my office window, the city still reminded me of a war zone. “What´ve we done to deserve this?”, I thought. It’s night time now and I haven’t been able to return home. I might do so tomorrow. (José, Rio)
Comment 3 - Worldwide, we are seeing more and more
climate instability. The deserts of central Asia are growing,
while areas of the US (and now Rio) are drenched. The lakes
in Minnesota have never thawed this early, at any time in the
recorded record. The icecaps will be history, and islands
around the world are disappearing under the surf. The oceans
are warming, the coral reefs are dying. How much more
evidence do we need of global warming? (João, Brasília)
There are lots of things you can do to save energy at home, from simple things like washing at 30 °C, saving water and
recycling, to insulating your loft and cavity walls. By saving energy you’ll be reducing your home’s carbon dioxide (
) emissions and helping to fight climate change.
Why should you save energy?
Over 40 per cent of the UK’s man-made
emissions actually come from energy we use every day – at home and when we travel. To generate that energy, we burn fossil fuels (coal, oil and gas) that produce ‘greenhouse’ gases – in particular
– which are changing our climate and damaging the environment.
The greenhouse effect
and various other gases wrap the Earth in an invisible ‘blanket’, helping to prevent heat from escaping. Without this greenhouse effect, the average temperature on Earth would be around -18 ºC, compared with the current average of around +15
ºC. This blanket of gases has remained at a constant concentration for many thousands of years. Since the Industrial Revolution
began around 200 years ago, people have been burning more fossil fuels. This has increased the heating effect of the ‘blanket’,
trapping more of the sun’s energy inside our atmosphere. In turn the Earth’s temperature has increased more rapidly in a shorter
period of time than it has for thousands of years.
The impact of climate change
People sometimes think that climate change will be a positive thing for the UK, giving us warmer summers and fewer cold
winters. But hotter summers and less rain in the south and east will mean water shortages, forest fires and damage to crops and
wildlife. In the north and west there could be much heavier rain and more flooding. As the polar ice caps continue to melt, rising sea
levels will threaten many coastal communities. Overall, the cost to society, the environment, our health and the economy is likely to
far outweigh any benefits.
Make a difference
The average UK household creates around six tonnes of
every year – that’s 6,000 kg – to heat and power their home. Making your home more energy efficient could save you up to £340 a year and reduce your home’s
emissions by up to 1,500–2,000 kg. You could save even more by switching to renewable energy sources, by walking, cycling or using public transport
whenever possible, and by driving more efficiently.
